Bursitis and Upper-Arm Pain

Reaching overhead, putting on a jacket, or lying on the affected side may aggravate it. Similar pain can come from shoulder tendons, the joint, the neck, or an injury, and several of these problems may coexist.

A shoulder bursa helps tendons glide beneath the bony arch above the joint. Irritation can make the space sensitive as the arm rises, producing shoulder pain that is perceived farther down the upper arm. Symptoms that extend into the hand with tingling or numbness may instead involve a nerve in the neck or arm.

Assessment may include neck and shoulder movement, tendon strength, the pattern of tenderness, and a nerve and circulation check. Marked weakness after an injury raises concern for structural damage. Imaging is chosen when examination findings make it useful, rather than being automatic for every painful shoulder.

Reduce repeated overhead work and heavy lifting that reproduce the pain, but continue comfortable arm movement to limit stiffness. Support the arm with a pillow at night and change positions if direct pressure hurts. Return to demanding tasks progressively instead of repeatedly pushing through sharp pain.

A physiotherapist can tailor movement and strengthening to the examination findings. Pain medicine or an anti-inflammatory may help some people but requires a suitability check. When symptoms do not settle, a clinician may consider an injection; accurate placement and a sound diagnosis matter because not all upper-arm pain comes from a bursa.

Call emergency services for upper-arm or shoulder discomfort with chest pressure, breathlessness, sweating, faintness, or pain spreading to the jaw, back, or either arm. Seek urgent assessment for a deformed shoulder, loss of circulation or sensation, sudden inability to raise the arm after injury, or fever with a red, hot, swollen joint. Ongoing night pain, weakness, or restricted movement merits a planned clinical review.

Ask whether the examination points to the bursa, a shoulder tendon, the joint, or the neck. Request clear guidance on safe reaching and lifting, the exercises that match your current strength, and when a scan or injection would change the plan.
