Yikes because the Dr. as well as me and my wife have narrowed it down to the lichen planus being caused by a high lysine dose...especially after you stop taking them...mine was 6 months after I stopped the lysine and my LP lasted close to a year after. Get .05% clobetasol ointment for the skin and a kenalog shot for the instant relief.
Haven't seen a bump in 3 years and have used the ointment twice in those 3 years. Only diet I live by is eat whatever you want so don't let people tell you to stop eating and drinking all your favorite stuff. I know I wish someone had said this to me when I was dealing with it. Just go to your Dr and ask for kenalog shot and clobetasol ointment. Done!
