Just wanted to check to see how you are doing? Were you able to get into your family doctor? Were they able to help at all? Hope you are doing better!
Could be something like dry skin, or perhaps that's where your clothing is rubbing up against you. If it's really bothersome, I'd encourage you to go to the doctor- they see a lot of things, and if something is bothering you, embarrassment shouldn't stop you for seeking out medical attention.
