Have you tried expert chiropractic , and/or someone that has a low level laser?
(also called soft /cold laser)
if you can find somewhere to try a laser, I'd try it first.
DC used it on my neck, shoulders, elbow, wrist, low back , even my foot for plantar fasciitis. Most times 20 sec per spot & pain was gone..

When we are hurting we often tend to walk/move favoring the sore area that can set us up for misalignments also..

Do you have or tried a TENS or IF stim? my IF stim was around $70 on Amazon..
