Hello,
Apply topical antibiotics like Neosporin on the boil and for the dry itchy hands and feet get contact dermatitis and pompholyx ruled out. The exact cause is not known and excessive sweating can be one of the reasons. But some triggers like allergic reaction to soaps, detergents, foods, latex, nickel etc may trigger the symptoms. Apply some calamine lotion on the affected area and keep the area well moisturized. Use only thin applications of moisturizer ointments as excessive amounts of ointment may restrict breathing of the skin and aggravate the condition.
Topical steroids can be applied but they are available under prescription. Moreover to prevent infection, topical antibiotics may be needed. I suggest you to consult a dermatologist and get it evaluated.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks for the advice and I have made an appointment for dermatologist , my hands started breaking out in 2000 off and on the cause started in culinary arts class when we had to dip dishes in a blue solution ... Yes my hands and feet sweat alot especially when im nervous ..
