L50.5: Cholinergic urticaria
When you are physically active and sweat, you get a rash on your skin. The rash can also be caused by stress, spices or alcohol.
The symptoms can vary in their severity. Certain areas of the skin usually swell up. These areas are often very itchy and red. The symptoms are similar to those that come from contact with stinging nettles.
The rash usually fades away again after a short time. The rash may keep appearing.
