Question: When I shower, and when I drink alcohol (even 3 sips), I get red in the face, knees, and almost hive-like patterns on my legs, but that aren't raised—just warm/hot and large blotches. What could this be a symptom of? I'm not necessarily looking to take any medicine, unless it's a big concern. I just can't figure out why. Also, my showers aren't that hot. I am prone to inflammation and want to get to the root of it. I'm not sure this falls in the asthma/allergy section, but it seemed to fit the best. I'm worried it's an autoimmune problem or something endocrine. • Chronic, low-grade, (seemingly) full-body inflammation (varies day to day), but not related to injury, which is often, extremely warm to the touch and expresses most in hands, feet, joints, and muscles. • Rashes and hives, varied in type, and seemingly unrelated to stimulus (sometimes, with hives, when under stress, lasting up to three or four months). • Hypersensitive: stress, food, perfumes, etc. • Psoriasis, diagnosed as a child (but in remission or misdiagnosed). • Possible continually high histamine level.
