my wife is a massage therapist . she had the rash on her hands and body 15 years ago and suddenly it has shown up again . I have made an appointment with the dermatologist but he won't be able to see her until the 12th of December. The rash has swollen her hands and they look as if she had burned them . We have tried over the counter hydro cortisone without any improvement also she says that the itching is unbearable at times.
