Hi jlogrange,
No, you are not alone. I am also 43 and have been suffering from chronic daily tension headaches since I was in high school......and have tried everything imaginable. Neurologists, chiropractors, physical therapy, psychologist, biofeedback, dry needling, massage, MRI's, CAT scans, X-rays, steroid injections, Rx's like Topamax, muscle relaxers, antidepressants, narcotics, anti-inflamatories....the list is endless. I actually stopped trying to figure out why I have these headaches years ago, but I recently moved to another state and thought I'd see if the doctors here could help me. Went through a lot of the same stuff I went through years ago, with no new outcome. Just this week I saw an orthodontist. He wants to do an occlusal adjustment on me because he says my bite is "off". I have horribly tense muscles in my shoulders, neck, head, and jaw. Massage and physical therapy have not helped...AT ALL! The muscles are constantly tense. I know that TMJ can cause these kinds of issues, but I'm afraid of sinking yet more money into treatment that may or may not solve the problem. But my husband says to try....at the very least, we can just cross it off the list of treatments that didn't work. I just get my hopes up and am disappointed when it doesn't work. Sorry I wasn't much help. I just wanted you to know that you aren't the only one, and I do understand.
