So it just started happening recently on my right leg about 2" below the bulky calf muscle and right above the tendon and slightly to the inside of the leg. It's kind of a pop, not like a bone pop, like a rubbing pop, doesn't hurt at all. Usually happens when I walk down stairs or when I'm doing calf raises and sometimes when I do squats. Should I be worried about this cause I really don't want anything to snap.
