Sounds like either an allergic reaction, or something harsh on your hands. First make sure you don't have any other symptoms like the rash spreading or difficulty breathing(go to dr. Immediately!) you can try soaking your hands in lukewarm water with epsom salts (painful, I know but may actually help) keep hands clean, and try hydrocortisone cream if it itches, or a triple antibiotic ointment and wrap in clean gauze or towel until you can get to the doctor, hopefully soon. You can take benadryl if it is itching, and ibuprofen for pain and swelling. Please call the dr. Soon, good luck:)
