I'm a begginer on bodybuilding, but there's something that doesn't let me workout at full potential, especially on my triceps. About 2 years ago I fell down and injured my right elbow, since then everytime I make a curl movement I feel (and sometimes even hear) a crack.  It happens in almost every arm workout, but it doen't hurt much. But when Im working on my triceps, it gets really, really bad. I feel strong pain that makes me stop working out, my elbow gets swollen, and it keeps hurting for a while.

What do you think would be the solution.I'm taking 1350 mg glucosamine a day, but i don't feel any difference. Should I look for expert help, or there is a good suplement that can help me.

I heard about Labrada Elasti-joint. Does it work??

Sounds like you should see your doctor and get that elbow examined and some tests ordered to make sure you dont have any degenerative changes going on in the joint or the surrounding tendons and tissues.
