from my experience: search for a good ART Practitioner in your area. here in San Diego, I see Dr. Mike Kuoppamaki and Dr. Sean Higgins.
I've been amazed at the issues they've been able to resolve...some that I thought were serious issues, they resolved in one sitting.
I can't say this will do it for you, but I've had shoulder issues, psoaz, and countless other injuries they've addressed...many of which I thought were serious.
also, if you're haunted by tendonitis...you really should try
Joint Rebuild or
Achilles...life changing!
