What could cause my upper arm to be swollen and sore?
Swelling and soreness in the upper arm may be due to injury, infection, inflammation, or circulation issues and should be evaluated if symptoms persist or worsen.
Explanation
Possible causes of a swollen and sore upper arm include:
Injury or trauma: Sprains, strains, bruises, or fractures can cause swelling and pain. Infections: Skin infections such as cellulitis or abscesses can cause redness, warmth, swelling, and soreness. Inflammation: Conditions like bursitis or tendonitis can cause swelling and soreness. Blood clots (deep vein thrombosis): Clots in the veins can cause swelling and pain. Lymphedema: Fluid buildup from lymphatic blockage can cause swelling and discomfort. Venous obstruction: Blockage or compression of veins may cause swelling and soreness.
If swelling and soreness are sudden, worsening, or accompanied by fever, numbness, or weakness, seek prompt medical care.
