You'd be right, can't be all normal. Did you see my reply to you where an RPA dr thought maybe your thing sounded like something? Callous something, i think, nope no search luck there. Try blisters in yours. Ah, that led to https://investorshub.advfn.com/boards/read_msg.aspx?message_id=176553060 .. not callous but bullous. Bullous pemphigoid.
How does that sound re yours? Wouldn't think it would be me as i didn't have (rash is virtually not visible now) big blisters as you described, and as the Bullous... looks to have. Though the envoplakin Eliza test they did on me .. https://www.google.com/search?client=firefox-b-d&q=test+for+Bullous++pemphigoid. .. is also one for that bullous problem. There would be heaps of overlaps, of course.
