I hope I spelled that right. A friend of mine has it and is having sugury soon. He still is having a hard time getting any detailed info, even from his Doctors.I do know that this painful ailment in which your skin can not heal. Other than that we are clueless. So I thought I would come to "Good Ole Trusty" drugs.com for some help. He is in much anguish, I would love to suprise him with some detailed info.BTW, he is a male in his late 50's if that helps. Thank you for your time.
