I would get yourself to a sport therapist. If yours is saying its now muscular it should help a lot. I see one in conjuction with the osteo and it is a great combo.
And just to second the vitamin D suggestion, please get it checked out and check B12. If its low you get those exact symptoms of tingling and numbness etc. And jsut like vitamin D its rarely tested and its even rarer for it to be treated properly. It also tends to run hand in hand with vitamin D deficiency.
