Is surgery best for posterior tibial tenosynovitis and tibial neuritis? Also I think I have prolapsed hemorrhoid and it burns..... Help

Orthotics. I wouldn't have surgery initially. Posterior tib tendonitis and tarsal tunnel syndrome is a result of flat feet. At your age, it is likely a flexible flat foot that can be corrected with shoe inserts or custom orthotics. Go to the store and try Dr. Scholl's orthotics before going to surgery.
