If it's improving with the measures you're taking, I wouldn't worry. If it's not, then if it were me I'd see a chiropractor who has or works with a good massage therapist. You've now twice mentioned the possibility of a structural problem with referred pain. Chiropractic and massage are the specialties that treat those conditions.


(I also wouldn't worry about the "TMI" on your MRI. Perhaps some Yoga or physical therapy to help re-align your spine and let the discs heal.)
