Husband has had a problem for the past six months - nine months. He develops a rash that is itchy on his arms, legs, chest and back. The rash is so itchy he can hardly sleep. Different spots each night. Most times the rash is accompanied by bumps. The rash and itchy spots completely go away by morning. We have not changed soaps, lotions etc. Also when he takes a shower, each time he has red marks on his back that look as though someone scratched him, after awhile they go away. He doesn't want to go to the doctor, but I am concerned what is causing this. Thank you for your help.
