Summary
Since getting COVID in 2020, this Reddit user had random itchy areas, especially where hair or clothing pressed on the skin; scratching raised dermatographia lines that faded after a few minutes. They said it was not allergies, but 180 mg of Allegra helped the symptoms. They asked whether it was mast cell-related or MCAS. The symptoms were still present in February 2026.
