I was just about to post about this. I am having this problem in my elbows. Started 3 days ago in my right elbow, and yesterday in my left. I've been taking Glucosamine & CSA for about 3 months now. Might hit up on the Ibuprofen tonight. I usually get this pain in my knees after a long ruck or 8-9 mile run(I'm severely flat footed), but never felt it in my elbows before.
