I have suffered with LS for 2 years and finally found some relief. I did the 'Fast Track Detox Diet' and after a one day juice fast (8 oz
cranberry juice + 56 oz
water as well as 70 oz
of water) I was itch-free, pain-free and had no inflammation. I mentioned this to my doctor and she told me that low-oxalate diet often helps relieve the symptoms of LS.
I am also taking Clobetasol (a steroid) which may not be what others on this forum are looking for, but it has helped tremendously (the fast was before I started the medication, so I was able to start symptom-free and it has kept me that way).
I am on a low-oxalate diet and hope that once I go off the steroid I will be able to maintain my normalcy (and if I need to do a juice fast from time to time it's definitely worth it). You can check out http://www.vulvarpainfoundation.org/lowoxalatefoods.htm

I hope this helps someone!
