I was getting worse and worse headaches almost daily and my neck was popping (aka 'adjusting') on its own. If i could get it to pop 'right,' the headache would go away for a while, but it would definitely come back later. If I couldn't get it to pop, or it popped 'wrong,' the headache would get worse, especially if it popped wrong.
I don't take many painkillers, but I was getting tempted to raid my wife's Vicoden & Darvon supply (story below - also chiropractic) since prescription levels of Advil (4 OTC pills) PLUS Tylenol (Xtra str) wouldn't fade the pain. I went to a chiro and their diagnosis was a reverse curvature of the upper spine. The spine above the shoulders is supposed to curve slightly forward, mine curved back. I had never liked pillows - usually slept with them on top of my head instead of under - and this explained why.
I went regularly for a few weeks and slowly tapered it off. They like to see me monthly to give me a 'tune-up' (his words), and I do go, but I can take time without going easily. Headaches are gone, I can still self-adjust almost at will though I try not to.
I think most people have some level of problem with their back, though most times it does not present any symptoms. Tough choice whether to believe their claims or believe its all a scam. I believe most times they're right on.
Re: My wife. She used to ride horses competitively 25-30 yrs ago. Hunter-jumper, Dressage, steeplechase, etc. She has gone over jumps without the horse, been thrown, etc. and basically disintegrated her coccyx (tailbone). One day 5-6 yrs ago she went to take a shower and stepped on the cat's tail while stepping into the shower (story in and of itself - this cat wouldn't drink from a bowl, it had to be running water) and both feet went out from under her while straddlling the tub. She came down square on what would have been her coccyx, but wasn't...
Turned out she'd fractured the last 3 vertebrate (L4,5&6 IIRC) and blown those 3 discs as well. She refused surgery (the only suggestion 2 different MDs made) as she'd had enough of that (another long story that started when she was 6) and they wanted to fuse all 4 bones (3 vert's and the remains of the coccyx).
After a few more months of pain & muscle relaxers, and being bedridden 24/7 (I had to help her get up to go to the bathroom), we contacted a Chiropractor (She used to work for a Chiro college) and while they recommended surgery too, they did offer the option of extensive therapy that should give her her life back without surgery.
The first adjustment was a miracle. It didn't last, and it was a few more months of daily therapy and adjustments with regular massage therapies before she could function normally, but normal she is. Her back still hurts sometimse, she eventually had steroid injections into the spine to stop the constant pain (that or be on Vicoden/Darvon 24/7), but she can ride horses again, operate the clutch in my car, etc. She still goes for adjustments once every 3 weeks, but is trying to stretch it to 4, and maybe she will succeed.
