My husband developed BP about a year ago after undergoing immunotherapy for melanoma. It’s been a daily challenge with blisters developing on various parts of his body, itching and discomfort. When blisters break and ooze (and sting!) special care to apply steroid cream and bandaid. His dermatologist is following him closely. Various steroid creams, course of doxycycline. Have not tried oral steroids (yet). There will be some improvement for awhile, then new blisters will form. So frustrating. He was told this may “burn itself out” in 5 years?? If this has happened for anyone out there, please let us know. In the meantime, sending out positive thoughts and prayers for all of you suffering with this.
