Thank you for your very thoughtful reply.

With respect to my bike set-up, I've had 2 fittings and I'm certain the bike fits me very well. I have never noticed any elbow or shoulder pain while riding. The shoulder pain began last September but I didn't notice it while riding until December -- even during a challenging metric century ride in November.The elbow never bothered me while riding. However ---- I had Kienbock's disease in my left wrist, which was treated with a silicon spacer put in in 1978. My right wrist has had similar symptoms (poor ROM, popping when the wrist is immobilized) and I've gotten conflicting reports on the x-ray/Wikipedia reference-linkMRI results as to whether Kienbock's is there or not. All of that to say -- my wrists are not 100%.

Could this be pseudo Wikipedia reference-linkTennis Elbow even if the standard strength and ROM tests for it are positive? Are the symptoms exactly the same in either case? Pain is on the lateral epicondyle. Oh -- and this is a recent development in the past few weeks --- now it also hurts to press on the medial epicondyl, but the 'tennis elbow' pain is much MUCH worse. I feel like I'm falling apart.

I will give serious consideration to my neck and upper trapezius -- but how do I find someone who sees outside the box and looks at the whole picture? Finding the right doctor is starting to seem as likely as winning the lottery.
