One day I was staying at a friends house and woke up the next morning with my underwear stuck to a small raw spot in my pubic area wear the hair grows. I had not cut myself shaving, nor was there a bump there before. I did not feel any irritation until I woke up and noticed it was weeping. There has not been any puss, no blood, but sometimes the raw spot gets irritated and slightly redish. I have been putting hydrogen peroxide and polysporin on it and trying to wear cotton panties. It's starting to heal slightly up now after a week but I still don't know what it was and if I should be worried? Is it from shaving?
