question: I have a lump on my inner thigh the size of a nipple. When I squeeze it, there is something inside like blood or pus. It is a bit annoying when I wear pants, the friction it creates. I have had similar and in the same location but never this size. I think its causef from chafing as I am 40 lbs overweight. Can u tell me what to do to make it go down until my dr appt in a week? I don't want to go to an ER...
