Why Does My Shoulder Hurt When I Raise My Arm? Causes, What to Do & When to Get Help

If raising your arm to reach a shelf, put on a shirt, wash your hair, or lift something overhead has started to hurt, you are not alone. Shoulder pain is a common reason people in Burlington look for advice and physiotherapy. Burlington residents have specifically discussed shoulder tendinitis, recurring shoulder problems, and finding help for neck, shoulder, and upper-trap pain.
Shoulder pain Burlington residents experience can make everyday activities surprisingly difficult.
The difficult part is figuring out why it hurts and what you should do next.
Shoulder pain can come from a number of different causes, and the place where you feel pain does not always tell you exactly what is causing it. This guide explains some common reasons your shoulder may hurt when you raise your arm, what you can try at home, when you should seek medical attention, and when shoulder physiotherapy in Burlington may be appropriate.
Shoulder Pain Burlington: What Could Be Causing It?
Important: This article provides general information and is not a diagnosis. If you have severe or unusual symptoms, or you are concerned about an injury, speak with a qualified healthcare professional.
Why Does My Shoulder Hurt When I Raise My Arm?
Raising your arm requires several parts of your shoulder and upper body to work together. Your shoulder joint, muscles, tendons and surrounding tissues all contribute to the movement.
Pain when lifting your arm can occur for many reasons, including irritation of the tissues around the shoulder, an injury, reduced mobility, weakness, or problems that develop gradually over time.
Some common possibilities include:
Shoulder tendon irritation
The tendons around your shoulder help stabilize and move the joint. Irritation can cause pain during movements such as lifting your arm overhead.
You may notice the pain when reaching, lifting, exercising, or performing repetitive movements.
Bursitis
Small fluid-filled sacs called bursae help reduce friction around joints. Irritation of a shoulder bursa can cause pain and make certain movements uncomfortable.
Rotator cuff problems
The rotator cuff is a group of muscles and tendons that helps stabilize your shoulder. Overuse, injury, or degeneration can contribute to shoulder pain and weakness.
Frozen shoulder
Frozen shoulder can cause increasing stiffness as well as pain. Everyday movements such as reaching overhead, reaching behind your back, or putting on clothing can become difficult.
Shoulder arthritis
Changes within the shoulder joint can cause pain, stiffness and difficulty with movement, particularly in older adults.
Referred pain
Sometimes pain felt around the shoulder is actually related to another area, such as the neck. This is one reason an appropriate assessment is important instead of trying to diagnose the problem yourself.
The NHS notes that shoulder symptoms can have different causes, including tendonitis, bursitis, impingement, arthritis, frozen shoulder, instability, and injuries affecting bones or tendons.
Why Does My Shoulder Hurt Only When I Raise My Arm?
This is a question many people have because the shoulder may feel fine while resting but painful during a specific movement.
When you raise your arm, the structures around the shoulder have to move and work together. If one of those structures is irritated or your movement is restricted, a particular range of motion may trigger symptoms.
For example, you might notice:
- Pain only above shoulder height
- Pain when reaching forward
- Pain when reaching behind your back
- Pain when lifting something
- Pain while putting on a coat
- Pain when reaching for something on a high shelf
- A painful “arc” while raising your arm
The specific movement that causes pain can provide useful information during an assessment, but it does not necessarily tell you the exact diagnosis by itself.
Why Does My Shoulder Hurt at Night?
Shoulder pain at night can be particularly frustrating because it can interfere with sleep.
You may notice that:
- Lying on the painful shoulder makes it worse
- Turning over wakes you up
- Your shoulder aches after a long day
- You have difficulty finding a comfortable sleeping position
Persistent nighttime shoulder pain is worth paying attention to, particularly if your symptoms are getting worse or your shoulder is becoming increasingly difficult to move.
The NHS recommends seeking medical advice if shoulder pain is worsening, does not start improving, or makes it very difficult to move your arm or shoulder.
Could Your Shoulder Pain Be Coming From Work or Exercise?
Yes.
Shoulder pain can appear after activities that place repeated demands on the shoulder, especially if you have recently changed your routine.
For example, symptoms may begin after:
At work:
Repetitive reaching, lifting, overhead work, or prolonged desk work.
At the gym:
A sudden increase in lifting volume, overhead exercises, pressing movements, or poor load management.
In sports:
Throwing, swimming, racquet sports, contact sports, or repeated overhead movements.
At home:
Painting, moving furniture, gardening, carrying heavy bags, or other activities that you do less frequently.
Interestingly, Burlington residents have specifically discussed shoulder problems related to activity and have sought physiotherapy recommendations for shoulder tendonitis and recurring shoulder issues.
What Should You Do When Your Shoulder Hurts?
The first step is usually to avoid making the problem worse while still keeping the shoulder moving appropriately.
That does not necessarily mean keeping your arm completely still.
For many common shoulder problems, gentle movement can be preferable to completely stopping use of the shoulder. The NHS advises staying active and gently moving the shoulder while avoiding activities that make the symptoms worse.
You can consider:
Reduce activities that clearly aggravate the pain
You do not necessarily need to stop everything.
Instead, temporarily modify movements that consistently increase your symptoms.
For example, if a heavy overhead press causes pain, it may make sense to reduce or stop that movement while you determine what is going on.
Keep comfortable movement
Gentle movement within a comfortable range can help prevent your shoulder from becoming unnecessarily stiff.
Pay attention to changes
Ask yourself:
- Is the pain improving?
- Is movement getting easier?
- Is strength returning?
- Is the pain spreading?
- Are symptoms becoming more frequent?
These changes can help you decide whether you need further assessment.
Should You Use Ice or Heat for Shoulder Pain?
Some people find heat helpful for stiffness, while others prefer cold for short-term symptom relief.
There is no single option that works for every shoulder problem.
The NHS suggests heat or cold packs can be used for shoulder pain, with a protective layer between the pack and your skin.
Do not apply extreme temperatures directly to your skin.
Should You Stop Using Your Shoulder Completely?
Usually, complete rest is not the answer for every type of shoulder pain.
Stopping all shoulder movement for too long can contribute to stiffness. At the same time, repeatedly pushing through significant pain can aggravate an irritated shoulder.
The goal is often to find an appropriate level of movement and activity.
If you are unsure what is appropriate for your specific shoulder problem, an assessment can help determine what movements should be modified and which can be continued.
When Should You See a Doctor for Shoulder Pain?
You should seek medical advice when symptoms are severe, persistent, worsening, or associated with other concerning signs.
According to the NHS, urgent medical assessment is appropriate for symptoms such as sudden severe shoulder pain, inability to move the arm, a visibly changed or badly swollen shoulder, persistent numbness or pins and needles, or shoulder pain that began after an injury such as a fall.
You should also seek medical advice if:
- Your shoulder pain keeps getting worse
- Your range of motion is becoming significantly restricted
- You have major weakness
- Symptoms are not improving
- You are concerned about a serious injury
You do not need to wait until the pain becomes severe before asking for advice.
When Can Physiotherapy Help Shoulder Pain?

Once serious causes have been ruled out or medical assessment indicates that rehabilitation is appropriate, physiotherapy can be useful for many shoulder problems.
A physiotherapist may look at:
- Shoulder range of motion
- Strength
- Joint movement
- Posture and movement patterns
- Neck and upper-back contribution
- How your symptoms change with movement
- Work and activity demands
- Your goals
The treatment plan depends on the findings.
It may include education, exercise, mobility work, strength training, activity modification, and a gradual return to normal activities.
Physiotherapy is not about giving everyone the same five exercises.
A person with shoulder stiffness may need something very different from a person whose symptoms developed after an increase in gym training.
What Happens During a Shoulder Physiotherapy Assessment?
If you are looking for a shoulder physiotherapist in Burlington, it is reasonable to wonder what your first appointment will actually involve.
A typical assessment may begin with questions about:
When did the pain start?
Was there an injury?
Which movements cause pain?
Does it hurt at night?
Has your strength changed?
What activities do you need to return to?
Your physiotherapist may then assess movement and function to understand what is contributing to the problem.
The goal is to build a treatment plan around your shoulder, your symptoms and your daily activities. AAOS – Shoulder and Elbow Conditioning Program
Do You Need Physiotherapy or Something Else?
Not every shoulder problem should automatically be treated by a physiotherapist.
Sometimes a doctor or other healthcare professional may be the more appropriate starting point, particularly when there has been significant trauma, unusual symptoms, or signs that require further investigation.
For other problems, physiotherapy may be a suitable conservative treatment option.
That is why a good article about shoulder pain should not simply say:
“You have shoulder pain, so you need physiotherapy.”
The more useful question is:
“What is causing your shoulder pain, and what is the appropriate next step?”
Shoulder Pain in Burlington: What Should You Do First?
For someone living in Burlington, the first step should depend on the severity and nature of the symptoms.
If the pain started after a significant accident or injury
Medical assessment may be more appropriate, particularly if you cannot move your arm or you notice major swelling, deformity, numbness or severe pain.
If the pain developed gradually
You may be able to monitor the symptoms while modifying aggravating activities and maintaining comfortable movement.
If the problem is not improving or is interfering with daily activities, an assessment can help identify what may be contributing to it.
If you are struggling with movement, strength or returning to activity
A physiotherapy assessment may be useful.
This is especially relevant for Burlington residents who want to return to work, exercise, recreational activities, or sports.
Local Burlington discussions show that residents actively seek recommendations for shoulder tendonitis, neck and shoulder pain, and sports-related physiotherapy.
What Can Shoulder Physiotherapy in Burlington Help With?

Depending on the assessment and diagnosis, shoulder physiotherapy in Burlington may help you work on:
- Shoulder mobility
- Strength
- Movement control
- Activity tolerance

How Do You Know If Shoulder Physiotherapy Is Working?
Recovery is not always a straight line.
Instead of measuring progress only by whether the pain has disappeared, look for functional improvements such as:
- You can raise your arm farther
- Everyday activities are easier
- You can sleep more comfortably
- You have better strength
- You can exercise with fewer symptoms
- You can work without repeatedly aggravating the shoulder
- You have more confidence using the arm
Pain can sometimes fluctuate during recovery, so your overall trend matters.
What Should You Avoid With Shoulder Pain?
Avoid repeatedly testing a painful movement just to see whether it still hurts.
Also avoid suddenly increasing your exercise volume because the shoulder feels slightly better one day.
The NHS advises against completely stopping shoulder use, but also recommends avoiding activities that make the problem worse and avoiding strenuous exercises or heavy gym equipment without appropriate guidance.
A gradual approach is often more useful than going from complete rest to a full workout.
Frequently Asked Questions About Shoulder Pain
Why does my shoulder hurt when I raise my arm?
There are several possible causes, including tendon irritation, bursitis, rotator cuff problems, stiffness, arthritis and injury. The exact cause cannot be determined from one symptom alone.
Why does my shoulder hurt when I reach overhead?
Overhead movement places specific demands on the shoulder. Irritated or sensitive tissues may become painful during that movement. An assessment can help determine what is contributing to the problem.
Why does my shoulder hurt but I did not injure it?
Shoulder pain does not always follow a single obvious injury. Repetitive activity, changes in exercise, work demands, stiffness, or gradual tissue changes can contribute.
Is shoulder pain from sleeping on my side?
Sleeping on the painful shoulder can aggravate symptoms, but nighttime shoulder pain can have multiple causes. If it continues or is affecting your sleep regularly, consider seeking professional advice.
Should I exercise if my shoulder hurts?
It depends on the exercise and the cause of your pain. Gentle movement may be appropriate, but exercises that significantly increase symptoms may need to be modified.
Can physiotherapy help shoulder pain?
Physiotherapy can help many people with shoulder pain by addressing movement, mobility, strength, activity tolerance and rehabilitation needs. The appropriate treatment depends on the cause of the symptoms.
How long should shoulder pain last before I get help?
If your shoulder pain is worsening, not improving, or making movement difficult, it is reasonable to seek professional advice. The NHS advises medical assessment when shoulder pain does not start improving after two weeks or is getting worse.

Start by paying attention to how the pain behaves, reduce activities that clearly aggravate it, and seek appropriate medical or rehabilitation advice when necessary.
For Burlington residents dealing with ongoing shoulder pain, reduced movement, weakness, or difficulty returning to normal activity, a professional assessment can help you understand the next step.
