My ex-boyfriend had develop red itchy welts on in body (mainly arms & on the top of his back) he said it first started a little over a year ago & disappeared now in the past 4 months he says it got worse. When he would put witch hazel on the red itch welts bumps it would calm down & then reappear shortly after (like a few minutes). He s got alot of allergies & allergic to alot of things (like ivory soap, cats, grass, coachroaches, dust..etc). He went to a asmtha & allergy dr this past week to determine what could be causing these itchy red bumps, welts. She did a number of skin tests the next day she did some blood work. Is this blood work for some more allergies or something more serious like skin cancer? I m very worried. He wont get the test back until a couple of weeks now a week & a half.
