I was doing bicep and hammer curls 2 days ago and on my left arm when I finish at the top of the movement I felt something, like a tendon or ligament move, it wasn't painful but I never experienced anything like it

Now there is a dull pain when I fully extend or flex my left arm. The pain is in the lower part of the biceps, near the inner elbow [palms up]

Is it a strain, soreness or what else can it be?


I am not sure if it's pain in the bicep or brachioradalis, but the pain is mainly concentrated when fully extended on the most left part of the arm beneath the bicep on my left arm.
