I have been on a 50 Mcg patch then lowered to a 37.5mcg fentanyl patch I change every other day. Occasionally if I'm having extra pain I will put the used patch buccally while I'm changing a new one. Lately I've been getting terrible rash around my chin and cheek and eye almost like acne but very red and sometimes painful and they get dry and itchy. Just wondering if it could be the from the fentanyl buccally? I have no issue from the area I put the patch on my arm and I always use same spot. It's the only thing I have done different in my life so curious if it's that or just maybe stress!!
