Hi,

It sounds as though it could be a muscle tear, although a moderate (or worse) tear doesn't usually occur from just walking.
When you say just started back at the gym, have you had another injury?
You say the pain is a couple of inches above the knee crease, is it central or more to the inside or outside?

Let me know and I'll try to help!
