Pain a little above elbow, on inside of arm - Tricep/tendon???

Hey guys, I'll try to give you as much info as I can about this injury, since it's really bothering me.

I have a slight pain when extending my arm from flexion. The location of the pain is on the inside of the upper arm (not forearm), maybe 1 inch above the medial epicondyle. It's not a sharp pain, its rather dull but well localized. If I increase the load on my arm (ie extend it against some more resistance), the pain doesn't seem to increase, although I didnt do it against much resistance.

I think I got this injury either from badminton, bench press or tricep exercises, although its hard to tell. Badminton definitely made something near my elbow hurt quite a bit, and I've since stopped playing, as the pain would sometimes last several days. During that time it was hard to really pinpoint the pain, but I think its this same location.

I really can't figure out what it is. Could it be coming from the elbow joint itself? Anyway if any of you have some ideas, I'd appreciate hearing them! Thanks!

I'll also add that the pain is intermittent. I can extend my arm (with no weight or resistance) and feel slight pain... or it could feel perfectly fine. Usually slight pain though.

Weird.

And more info!

My triceps seemed to be ok strong before this, I'll mention. I used to do pulldowns and skullcrushers with up to 65 pounds each, but now doing tricep pushups (with hands close together), even off a wall, produces a little pain.
