I think I’m experiencing a mast cell hyper reaction to hair dye.

Seven weeks ago, I had my hair colored and had an allergic reaction in my scalp that persisted. Last week I developed a systemic reaction with a rash all over my torso, done areas tiny bumps, others large. All extremely itchy. I’m 4+ years Long Covid. Had a similar rash on my chest and arms a couple years ago. But this is so much worse. I’m afraid it’s in my eye at this point. Anyone else experience something similar??
