Is it normal for my arm to swell after working out?

After exercise, especially if it involves the arms, you might notice:

Temporary mild swelling: Increased blood flow and fluid movement into muscles during and after activity can cause slight swelling. Muscle pump effect: The muscles temporarily hold more blood and fluid, leading to a feeling of fullness or mild swelling. Minor muscle strain: Overuse or small muscle injuries can cause inflammation and swelling.

However, if swelling is severe, painful, lasts more than a day, or is accompanied by other symptoms such as numbness, weakness, or skin changes, it’s important to seek medical advice. This could indicate injury, nerve issues, or vascular problems.
