Feeling your pain, I suffered for a year or two with alot of pain.
Get physio, this will hurt. But you should be pain free for a day or two afterwards.
Hit the weights big time. DB press, deadlifts, rows.Heavy and hard, power lifting type movements.
No supplements make that much differnce really, but knock yourself out.
Tried, mega dose vit c 5g day plus. Devilsclaw.Udoes oil. Glucosimine, chondtin, cisscus. May help out alittle.
Good luck.
