Whats wrong with my arm?!

Whats wrong with my arm?

well i have a problem.
my arm pops and makes snaping noises when i move it from left to right ( like side to side)

and it swells after sports such as soccer (i play goalie)
and sometimes i can't move it

also when it pops and makes noises when i move it left to right
my elbow starts to hurt.

plz help
thank you

depends on how long has it been hurting for, if its been like this for a while then you probably have inflammation of your tendon or ligaments and by playing sports you keep on re-inflaming it, so take nsaids[Advil, Motrin 600 mgs every 8hrs] and if you are a small guy decrease the dose and rest it for 3-6weeks and it should go away and if you have insurance and you wana go to a doc get an x-ray better yet an MRI [much more costly but very accurate imaging technology] that would be fine too...feel better
