Shoulder Pain in Both Shoulders: When It Might Be Inflammatory (PMR, RA)

Two sides of the body can be affected by the same cause. Inflammatory conditions can involve more than one joint at a time. That is why a doctor will look at the pattern, not just the painful spot.

Mechanical causes, such as tendon or joint problems, can also affect both sides. The pattern of pain, stiffness and other symptoms is what helps a clinician decide. You cannot reliably sort this out from a list on your own.

Rheumatoid arthritis is a long-term inflammatory condition that affects the joints. It is diagnosed and managed by doctors.

Polymyalgia rheumatica is an inflammatory condition that a doctor diagnoses. It is linked with pain and stiffness around the shoulders and hips. The evidence on its causes varies, so ask your clinician for the details that apply to you.

• Diet can be part of managing inflammatory joint conditions, but it complements medical treatment and never replaces it [R23].
• Omega-3 fats show a modest benefit in rheumatoid arthritis, according to the NCCIH summary [R20].
• For most other supplements, the NCCIH summary finds the evidence insufficient [R20]. Check with your doctor or pharmacist before starting one. This is especially important if you take blood thinners or other medication.
• Most shoulder pain is managed in primary care with advice and exercise. Severe pain after an injury, or any pain with red-flag signs, needs proper diagnosis [R30].

A doctor usually starts with your history. They will ask when the pain began, what makes it better or worse, whether it is worse at night or in the morning, and whether you have other symptoms. Tell them about any medication you take, including supplements.

Next comes an examination of both shoulders, and often the neck and other joints. The doctor is looking at the pattern of movement and tenderness, and whether the problem seems to come from the joint, the muscles, or a wider condition.

Some visits include blood tests. Imaging, such as an ultrasound or scan, is not always needed. Evidence on which tests suit which situation varies, so ask your clinician to explain the reasoning for any test they suggest.

Bring a short written list. Include when the pain started, how long each episode lasts, any fever or feeling unwell, and what has helped so far. A clear list makes the visit more useful for both of you.

1. Book a visit with your family doctor. Describe both shoulders, how long the pain has lasted, any morning stiffness, and any other symptoms, such as fever or pain in other joints.
2. Note the pattern. Write down when the pain is worst, whether it wakes you, and whether other joints are involved.
3. Ask about a referral if it is needed. Your doctor may refer you to a rheumatologist, a specialist in joint and inflammatory conditions.
4. Ask before you take supplements. If you are considering omega-3 or another supplement, talk to your pharmacist or doctor first. Talk to them especially if you take blood thinners or other medication.
5. Rest in a comfortable position. Avoid pushing movement into sharp pain while you wait for an assessment.
