Hi, I have been experiencing a single sore on the outside of the opening of the vagina. It is painful to touch or wipe with toilet paper but otherwise it isn't painful when I urinate. I have never had any burning or pain when I urinate. The single sore lasts only 2 days every time, and sometimes when one goes away, I'll get another one. There is always only one, but sometimes it is on the right side or on the left. I'm not sure if it is even an actual bump and if it is it's very small. There is no puss, they never rupture they just go away. I also seem to get lumps under the skin in the groin area which seem to be either cysts or swollen lymph nodes, these also last for 2 days and always go away on its own these are not painful at all. I wear tight underwear(thongs) and they are not always cotton I feel they may be a cause. I also have been shaving for about a year now and I get irritation, I don't remember getting so many sores or lumps when I was getting waxed. What could the sore be? Could the sore and these lumps be connected?
