Lateral epicondylitis, tendinopathy with multiple tendon ruptures along extensor tendon. treatment options?

That is a very com--: Plex problem that you have. Is it in the same arm or elbow area? Is this from an injury? Without being seen ; examined/investigated, its difficult to address all your issues in a meaningful way. You need to see an orthopod or a elbow/shoulder surgeon to get the best advice, as otherwise you'll get a pot pouri of suggestions, which may or may not help. Good luck.
