So today my dad looked down at his arms and realized his arms had broken out in hives. Before that he had touched the sweat shirt I was wearing. Later that day i patted my hands on my sweatshirt and instantly my hands looked like the skin on it was dying and it itched. The itch went away after a few seconds but the dead skin look stayed for about an hour. I soon made the connection and went to get my microscope. Infortunetly due to the microscope being cheap I couldn't focus it. Could these possibly be u hairs.
