I was diagnosed with LP in 2002 with burning mouth and sores in my mouth and spots all over my hands and arms. I have never known any who even heard of LP. Mine was caused from Prilosec meds. I have several medicine and food sensitivities. My dermatologist had a nurse call me by phone and tell me of the diagnosis and did not offer any treatment. I read about it on line at Mayo Clinic. I immediately stopped eating any preservatives food additives and stopped hair permanents. Ate natural foods. If took over two years to clear. Would get an occasional breakout bubble in the lining of the mouth. I recently had cataract surgery and took an inflammation medications for two months. My face and mouth broke out again. I was sent to an oral surgeon to check for cancer. He said it was my LP flaring up. I am still on my clean food eating and meditating to keep stress down.
