you're exactly right about what a doc would say/charge. he'd say that you have a bad case of Lateral epicondylitis (tennis elbow) and possibly bone spurs in the elbow region. He'd say lay off of it for a couple of weeks to a month, ice when sore and he'd have ultra sound done on it. i think you might be the one that posted about it hurting when you jab punched? not sure, but when you jab, your elbow should never pop to full extension. thats hyperextension. the same should occur in your throwing motion. yes i know that your arm will fully extend, but you should have already thrown the disc by then. if you wait to long to throw/rip/let go of the disc, then you are creating that pressure in your elbow. try taking it easy for a week or so, ice when sore, maybe take some anti-inflamintories if needed, stretch your wrist, forearm, and your tricep muscles. after if feels better, try and do some weight work (dumb bells) with your wrist, forearm and tricep.
