@rashida, my diagnosis was burning mouth syndrome. I wouldn't describe my feelings like razor cuts. My mouth, tongue, and lips felt like they were on fire. In the winter, I used my cold hands to press on my lips and I sucked on ice for inside my mouth. I kept telling the doctors that the inside my mouth felt like a garbage can. Not sure why I chose that comparison. That is under control with the Clonazepam. Razor cuts would describe what is going on in my vulva area. That was diagnosed as lichen sclerosis. I surely have not been cured of that. I do not believe there is a cure. I go from one flare to another very rapidly. I use Halobetasol and a compounded numbing ointment. Prior to that, I used Lidocaine/Prilocaine to numb. My scalp does burn and I use Head and Shoulders shampoo. My dermatologist just said I had flaky scalp. Nothing really helps that, but my PCP recommended 20 mg. of Amitriptyline at night. He was hoping it would help both areas. I suppose it could be worse, but sitting can be very painful. Sometimes I sit on an ice pack. If I were you, I would drop eating any mushrooms. I wonder if there is any connection between lichen planus and lichen sclerosis. I will have to look into that. I am sure you are as tired as I am of looking for help. Onward and upward! @joybringer1
