What should I do if I experience left arm swelling and pain simultaneously?
If you have swelling and pain in your left arm at the same time, it’s important to seek medical attention promptly to determine the cause and prevent complications.
Explanation
Swelling and pain in the left arm can indicate several conditions that may require prompt care, such as:
Blood clots (deep vein thrombosis): A clot can cause sudden swelling, pain, and redness. Infection: Cellulitis or other infections may cause painful swelling with warmth and redness. Injury: Sprains, fractures, or muscle strains can lead to swelling and pain. Inflammation: Conditions like arthritis or bursitis can cause joint swelling and pain.
While waiting for medical care: Rest and elevate your arm to reduce swelling. Avoid using the arm for heavy activities. Apply cold compresses to ease pain and inflammation.
If you experience chest pain, shortness of breath, or sudden weakness, call emergency services immediately.
