My 34-year-old daughter has suffered for about 10 years with hard, seemingly callused, red bumps, filled with pus, on both arms. The skin on the rest of her body is beautiful. She has seen many doctors, three of therm were dermatologists. She has been "diagnosed" with prurigo nodularis, even though these bumps have never itched! Her allergist treated her for an infection. The antibiotic gave a little improvement but just for a short time. The last dermatologist took a sample and treated her for pseudomonas folicultiis. The antibiotic, which she took for seven days, gave just slight and short-lived relief. She has also used clobetasol, which seems to help just a little also.
Maybe it's not a dermatologic problem. Should she see some other kind of specialist? Needless to say, she has tried to think of anything she uses or that her arms come in contact with that is different from the rest of her body. She can't come up with anything.
Other than this problem, she is in excellent health. She is 5'7", 155 lbs. She eats healthful foods -- no crazy diets or no-calorie sweeteners. She does have a rather stressful job in private industry -- not extreme stress, just the usual deadlines and such. She is so conscientious that she probably worries more than she should.
Please help. Thanks in advancd
