Keep researching the possible triggers of your ELP and treatment options. I discovered the connection between my ELP and my Rx for occasional heart palpitations... metoprolol. I discussed it with my primary physician who had put me on it years ago, and he agreed that I could gradually reduce the dose until I was off it. As a result, the lesions on my back, which I've had for years, have cleared up 90%. And even by oral lesions have improved.
