Curious if anyone has encountered this:

I am an avid "crossfitter" and weight lifter. I wouldn't think that I have weak ligaments or tendons.

Twice now in about 3 years I have experienced pretty profound, although temporary, pain on the interior of my elbow joint, where the bicep meets the forearm, generally where one would give an arm IV. It feels like a dull ache and throbs after vigorous activity. I developed it for about a week during a combatives certification and it went away with R.I.C.E. I brought it on again yesterday by some vigorous rope climbing and exacerbated it by playing football. It doesn't last long after activity but it interrupts my training regime during it and is bothersome.

My question is more for my education. Is this brought on by muscular, tendon, or ligament issues? Is it micro tears leading to strain? Lack of stretching/flexibility?

Most importantly, if anyone is familiar with this, are there some things I can do to strengthen this weak link and prevent recurrence?

I'd appreciate any input.
