What should you know about right arm pain from shoulder to forearm?

A shoulder tendon problem can make reaching overhead, dressing or lying on that side painful, with discomfort extending down the arm. Neck nerve irritation may send pain farther along the arm and may add pins and needles, numbness or weakness. Forearm tendon irritation, such as Tennis Elbow or Golfer's Elbow, is more tied to gripping and wrist movement. Pain that changes with posture, neck movement or arm position gives a clinician useful clues.

Avoid heavy overhead work and repeated forceful gripping while the pain is active, but do not hold the arm completely still. Use short periods of comfortable movement through the shoulder, elbow and wrist. Adjust screen, desk and sleeping positions if they reproduce symptoms. A physiotherapy assessment can examine the neck, shoulder, arm strength and sensation and then progress exercises gradually. Do not stretch into sharp pain or persistent tingling.

Seek urgent help for sudden arm weakness or numbness, facial drooping, speech difficulty, severe chest pressure, breathlessness, faintness or unexplained sweating. Prompt assessment is also needed after major trauma, with a deformed limb, a cold or pale hand, or rapidly increasing swelling. Book a clinical review if symptoms persist, disturb sleep or limit ordinary tasks.

Could the neck be referring pain into my arm? Do my strength or reflexes need checking? Which shoulder and neck movements are safe? What work or sleeping changes should I try, and when should imaging be considered?
