That sounds similar to the problem I had and ran for months on it as I found after about 5 miles the pain went numb! Little did I realise at the time the damage I was causing
Oesteopath - I saw one when injured and he was brilliant ( had a not great time with physio though that may have been due to actual practitioner) - I guess either are good - just a case of finding one that suits your own specific needs- good luck
