I went off many meds as well after a C1-C5 fusion, a craniotomy, a craniectomy, meningitis, infection of the bones, discs, and brain and a bunch of other stuff about a year ago - a couple narcotics, an antidepressant, and a muscle relaxant. I can definitely relate to the symptoms you're describing. It wasn't a fun couple weeks. I've found exercise seems to help the most. Various stretching and strength training and general cardiac exercise (jogging or walking). I also still get lidocaine/steroid nerve blocks every month. Other than that, I only take naproxen or Tylenol. Occasionally a tramadol or oxycodone if things are really bad, but those times are pretty few and far between.
