Have you had any expert PT or chiropractic?
How is your upper body posture?
forward head/rolled shoulders? hunched etc?
If so work on those and see if things improve for you.

Check out our sticky threads for more info on symptoms, testing & therapies.

Any previous sport injuries, whiplash, falls hits to upper body?
What do you think might have brought your sx on?

I didn't need any indepth testing as my symptoms did improve with good PT , DC and lots self care -plus off work..

My version is/was RSI based with a long time ago whiplash/concussion as a teenager, and lots of rough housing backyard sports as a kid.. had many falls, hits, bumps and such to make for some misalignment's that seemed to show up as I hit middle age + the repetitive fast paced job..and my type A competitive nature...

Sharon Butler's website , book & TOS program was very helpful for me - she has really good articles that explain the fascia connection..
