No problem Christine.
Is the skin with the rash smooth or raised or flaky?
Any tenderness or itching?
OK. There are a few possibilities here. Since it isn't at all itchy it doesn't sound like either a fungal/yeast infection or an allergic reaction, although those are both still possibilities.
If it's tender it sounds more like cellulitis--skin infection.
For now, you can try some oral benadryl and apply Eucerin or calendula cream three times a day and see if it subsides in a day or two.
If it doesn't, you should have a doctor take a look at it since you might need antibiotics
Let me know if you need any more information please Christine
