Try Graham Brown at the Royal Orthopaedic, he is an orthopedic physician so no knives. He is an ex RAF doc and knows his stuff.
He is a sports injury specialist, i had a back problem that went on for 5 years, saw 4 ortho surgeons and a neuro with no chance of a fix. The only help was a local oesteo but it usally only helped or a few weeks.
This doc diagnosed me correctly and offered a treatment with 90% chance of 100% fix. My problem was ligament damage, he used prolotherapy and after about 9 months it was pretty much back to normal.
Basically its a way of tightening and strenghtening ligament, worth a look anyway.
All the best gents.
