I know you can't afford it, but in this case, consider seeing a GOOD chiropractor.
After I did my dental cleanup (darn expenisve), my neuralgia pain improved tremendously. Iodine fine-tuned the job, and my Chiro rid me of the now much fewer migraines. Acupuncture helped, as well.
Bottom line is, health is our most precious asset, is it not?
