You do need to consult a knowledgable dermatologist or, better, an allergy specialist. We can suggest a renowned one in Chicago if you're anywhere nearby.
My wife suffered for several years from
greatly uncomfortable - through not dangerous - symptoms until she had an extensive series of allergy tests, and discovered there are a bunch of unlikely things she's allergic to. (I know, Winston Churchill said he hated ending sentences with a preposition. He's not likely to read this.)
She was discovered to have allergies to a lot of surprising things, like latex, cinnamon, gold (fortunately, her extensive

jewelry collection is silver and her wedding rings are platinum) and several common preservatives like sodium benzoate, which we can avoid fairly easily by carefully reading food labels and getting stuff like pickles at TJ's or WF.
The most annoying is these is her relatively recent allergy to capsaicin, because we both like spicy food. Now, we both have to skip it or cook separate batches for each of us.
This is not something to ignore. Good luck.
