I have had an underarm rash for 10 days. As soon as it started, I quit deodorant. I tried a triple antibiotic, also a moisturizing cream. It seems to have gotten worse. I want to see a dermatologist but it takes forever to get an appointment around here. Any help will be greatly appreciated.

Don't use any moisturizing cream, any creams or lotions at all, they will only cause more irritation, for sure. I would also discontinue the anti-bacterial cream as well, as that's mean to fight bacteria, not reduce a rash problem. You should try to wear clean dry cotton shirts to ensure no further irritation. If it is very painful and swollen or itchy, take an anti-inflammatory pain killer to reduce the discomfort.
