Thanks for posting your query at DoctorSpring.com.
I have read your question with diligence.
It looks that you are having trochanteric bursitis.But you are not getting symptomatic relief from this.It looks that you are not attacking at root of the problem,this is the reason why it is recurring. There are some other reasons to have this problem like obesity,thyroid disorder,psoriasis,rheumatoid arthritis,arthritis at hip,etc.You should ask from your orthopedic doctor to get yourself reevaluated.
Having yourself evaluated from the rheumatological point of view with help of blood investigation will be helpful for you.Till then you may have contrast bath(alternate cold and warm fomentation) and a good analgesic like combination of tramadol with paracetamol will be helpful for you.
Please feel free to discuss further,
With best wishes.
