Hi - sorry to hear about your frustrating discomfort.
I heard form a couple of people that balacing their minerals - specifically magnesium - was a radical cure for them. Check out the "ask Moreless forum for some very critical info on balancing your whole body. Easy starting steps and very clear.
One person I was speaking with recently had the same complaint - it had been two and a half years, and nothing had worked.
I sent her a suggestion recently, and she said all is ok finally, she said she's been drinking Noni Juice. Maybe that will help you?
Anyhow, following is the original post I had directed her to, I believe in this product becasue it has been used for so many years for so many things. The times I have used it, [for different purposes] it worked as promised and it is extremely soothing: Castor Oil Packs.
here is a link to a post by Molly Bloom with some info [and a link to write up]:
