Rotator Cuff (What to Ask/Say to Doctor, Tandem?) in General Skydiving Discussions September 28, 2010 Sorry for the delay in updating: The doctor, after an X-ray, sent me to a specialist who ordered an MRI. They still don't know what's causing the injury, though. There are no tears or cysts and the whole shoulder "looks great." There are two rotator cuff muscles on my right side that are very weak for no apparent reason. Up next, I will be tested for nerve issues. The doctor also said that I can jump again as it won't make the situation any worse (I think I'll try a tandem again first, just to see if the problem persists). She also said that she suspects the injury will just vanish in time. More info when they finally figure it all out.
