I have this skin irregularity that looks almost like i was stung by a jellyfish, but i haven't and it it painful
and only on the right side of my body (arm, side, leg). Blisters as well and i am extremely fatigued. It is not shingles and the doctors cannot figure it out. I have been tested for lupus and several other conditions and checked out by a dermatologist who can not even figure it out. I am 47 years of age, male, and otherwise in good health that is up until the past 6 months or so. Please help.
