My husband has itchy bumps appearing pretty much all over his body, scalp, torso, hands, arms,legs. 5 days ago he walked thru the wooded area behind our house, his is very aware of poison ivy and what to avoid plus the bumps appear with a tiny white head on them. He was wearing jeans, boots and tshirt at the time. Pretty much when he came in, he sd his arms and hands were tingling and starting to itch. The itching is almost unbearable for him!! Benadryl gives some relief but makes him so light headed he feels nauseous. I am very allergic to poison ivy and these are not clusters not blisters nor weeping.
