I am a 75 year old woman who has had LyP symptoms for 50 years. I finally got a biopsy. I don't understand why so many of us had to wait so long to be given a biopsy. Originally I was treated with prednisone, which led to prednisone induced diabetes, which then led to chronic kidney failure and then to dialysis. Prednisone was the only medicine that has ever been used for me. I believe, since it takes so long to do a biopsy, that this illness is not as rare as it may seem.
