Hand, Wrist, And Arm Pain While Exercising
Most exercise-related pain is dull and spreads over a larger area of your arms or legs. This is normal. When it seems to be sharp pain focused in one spot that you can pinpoint with a finger, it may indicate a muscle strain of a tendon inflammation. Popping, clicking, or grinding in the muscles or tendons are signs of strain.
