dermatographia since i was about 15 yrs old (22 yrs ago),I remember the doc taking one look at what i could do with my skin…said that’s interesting & put me on atarax(hydroxizine) 4 x a day. my kids think it’s COOL, when they were little they would “write” on me. They are now showing signs…not raised yet like mine is, just red lines on their skin.
Yup, that’s what that is! If you are symptomatic with POTS, DEFINITELY look into mast cell activation disorders, OK? There’s an article with the latest protocol on this site under “handouts” on the first page. It’s amazing how under- diagnosed this is!
