I don't know, but check on-line and see if there's anything you can do diet-wise that might help. It might be as simple as eating/deleting something or taking a suppliment. It won't solve a life-long issue, but it may help make it tolerable. I have the Guide to Nutritional Health, but it might be in storage. If I have it available to look at, I'll see what it says. You can go to any health food store and take a look at it there as well. Some of the suggestions in it have helped me in the past.
