farking SLE's and pulley bars! i have the same problem, inside and out of both elbows, severe pain in my right shoulder. shoulder pain (confirmed via MRI) is result of partially torn rotater cuff and SLAP tear (superior labrum anterior posterior-basically torn cartillage). while only a 3 on a scale of 1-10 the pain is a SOB! even normal sleep becomes an issue because at nite everything tightens up, elbows and all. come morning i can barely reach up to wash my face. after i start to move around a bit it gets better, not much, but better to the point that i can function...and kite!
my doctor is an avid surfer/friend and recommended that, while he is ready to surgically fix it, i should wait until it gets worse seeing as either way i will be in dry dock for a couple of months. basically he said i have to decide how much pain i can tolerate before i have to quit for the rehab...that or quit doing whats aggrevating it all together...like thats going to happen, right?
rehab (strengthening and stretching) helps, but kiting everyday becomes a little counterproductive.
its hard to rehab an injury when an hour after working with the PT the wind starts to blow!
