What steps should I take if my left upper arm is swollen?

Swelling in the upper arm can result from injury, infection, inflammation, or circulatory issues. Here are steps you can take:

Rest the arm: Avoid heavy lifting or repetitive movement that might worsen the swelling. Apply a cold compress: Ice the area for 15–20 minutes at a time to reduce swelling and discomfort. Elevate the arm: Keep it raised above heart level when possible to promote fluid drainage. Monitor for other symptoms: Watch for redness, warmth, fever, numbness, or spreading swelling. Take over-the-counter medication: Nonsteroidal anti-inflammatory drugs (like ibuprofen) can reduce pain and swelling.

Seek medical care if: The swelling is severe or came on suddenly It’s accompanied by pain, fever, or warmth (possible infection) You have a history of cancer, recent surgery, or blood clots The swelling lasts more than a couple of days without improving

Prompt medical evaluation can help determine if the cause is minor (like a muscle strain) or more serious (like a blood clot or infection).
