I can't find any information on this, since all the web info seems to be on bicipital tendonitis (proximal, long biceps tendon in the shoulder area). I think I have tendonitis in the other biceps tendon (distal - the one in the elbow area that attaches to the radius).
Not 100% sure if that's what it is, but I remember reading something a long time ago about it -- something like heavy deadlifting along with heavy benching in a high volume/high intensity workout phase can bring on this kind of pain.
Pain comes mostly from heavy bench workouts (I'm bulking now, so workouts involve high intensity / high volume). When the pain gets really bad, it affects all of my workouts, and pretty much prevents me from benching heavy.
Anyone else experience this, and if so, I'd appreciate any advice that you could give.
