I had a kidney stone blasted and had a stint placed to help the fragments pass. When the stint was removed Iodine was applied to the vaginal and anal area. Lidocaine was also used for deadening. After this I developed a skin condition in this area. It appears dry and crusty and itches really bad at times. I have used prescription Hydrocortisone and the itch slowed down a little but the condition has not changed.
