Nonstop itch out of no where

32 - 5’2, 140lb female. No medications but was on supplements (homocysteine supreme (was daily), CORTISOLV (sporadic), maca root (pretty regular) and fish oil on occasion - stopped these weeks ago) now just melatonin .5 and D-Hist. I do have seasonal allergies. Nothing else.

I’m itchy. All of the time, unless I take an antihistamine. About 3-4 days after my last histamine the itchy starts again. I was diagnosed with dermatographia, which is new to me. I do get the contact hives/rashes which started back in Feb 26, but that’s never the itchy part. It’s mostly my privates, scalp, neck and chest. Plus an all around just discomfort, literally tingling itch feeling. Especially in the middle of the morning or when I’m relaxed.

I’ve had every lab under the sun tested that I’m aware of. Thyroid was fine. I have tried to cycle through every possible allergen. Even had bloodwork done for food panels.. nothing comes up.

I’ve always had dry skin but never ever experienced anything like this in my life. Been through 1 OBGYN, 2 derms, 1 functional doc and 1 allergist.

What in the world could be causing this and how do I stop it? It came about at the end of Feb 26 when we got that randomly warm/hot weather. Has not gone away but severity is slightly better.. or it’s just cuz of the allergy pills.

One doc said they think it’s hormonal, I came off the supplements 3 weeks ago but no real progress. Others said just take allergy pills and hope for the best. But this is driving me insane and NO MATTER what allergy pill I take, they make me feel SO groggy.

If I start itching I won’t stop, especially “down there.” Any insight is appreciated. I’m going nutty.
