I am 20 weeks pregnant and just the other week I noticed an uncomfortable feeling on my right butt check every time I sat down. I didn't think much of it. But now entering into my second week it has become more uncomfortable, it is painful to sit down and walking as well, it is just very sore. I had my husband look at it to see if he noticed anything and he said it was like an invisible bump that was hard. Our guess is it could be a boil but we are no doctors. Any suggestions would be very much appreciated.
