I Have Hailey Hailey Disease..for 16 Years...I Most Recently Visited

i have hailey hailey disease..for 16 years...I most recently visited a dermatologist who recommended bandaging the spot on my groin as it was blistered...the bandage adhered to my skn and tore my skin off in that area..I have an ointment and hydrocortozone 2.5 cream...but only topical treatments...how can I heal my skin...there is major movement, friction and pain with every move I make...feels like a burn
