Rashes Spreading On The Body. Using Fungal Cream. No Allergies. What Else?

Hello, my name is Donna & I have had a rash on my chest and now randomly on abdomen area as well. It started as a heated prickly feeling. They are red bumps, some larger than others. At first I thought it was a fungal rash and have been using a cream called Hydrozole and another called Clonea to no avail. Have also tried natural healing antiseptic. These small bumps seem to form a tiny head, then small scab. Have an appointment at Dermotologist but not for 2 weeks. Do you have any suggestions. I have never been allergic to anything in my life ( I am 57). No foods or creams or skin products have never affected me so I am at a loss..............thankyou
