I have exercise induced urticaria and I started drinking organic ACV in organic apple juice first thing upon rising. You wait 15 minutes before eating anything else. I also bought a filter for my shower head to filter out the chlorine. I am also going to try a salacylic acid wash. This all helps. My spots are much smaller after a workout now. The measurements are about 1-2 tbls ACV in about 2 oz. Apple juice.
