I,m really sorry about your GD I have had this for 6 yrs it;s no fun I check this site about twice a week hopping that somone can help me. please forgive my spelling. anyway I have found a treatment that works for me . I wi ll be 80 in a couple of weeks i use a cream for poison ivy. At least I can sleep most of the night. it may not work everyone. but it works for me. I,m not a doctor so I don,t want to give anyone the idea that what I do will help. GDgd,
