Have you considered any expert bodywork or expert chiropractic care?
I had the best results from a multi modalities chiropractor. ( did ultrasound/deep tissue/LLLT/IF stim)
If you have any sort of accident or fall I really suggest chiropractic and/or upper cervical (atlas/axis/c1 c2) chiro check up.
