You do not really provide enough information. What tests have been done and what has been ruled out? Did you have any fever or generalized illness that preceded the problem?
Have you seen a rheumatologist?
Have you had Lymes disease ruled out?
I would also reccomend trying to find a physiotherapist who is an IFOMT (international federation of manipulative therapists) member and has sports physiotherapy experience to get a musculoskeletal assessment from a physio with advanced training. They should also be able to advise you if there are problems with neural irritablity and if they derive from a source the physiotherapist can treat.Ideally, I would try to find a physiotherapist with advanced manual therapy training and acupuncture skills.
Good luck. Marj
