@shopkin3, I'd check with the vet because she probably needs and antibiotic. I had laparoscopic gall bladder surgery, and over a year later, I developed a very inflamed lump under my belly button that looked like that. After starting antibiotics and applying hot compresses, it drained leaving a small hole in my belly. Well, at the time, I could still see that low on my belly and notice something black inside. I went to the doctor, and he discovered that my body was rejecting the permanent stiches used during surgery. The point I'm trying to make is it may be part of a stitch that was left behind. 4951
