Last weekend I had a bump that looked like a bite just below my waist. Well, it started filling up with fluid and was very painful. I went to the Dr. today, and he said that it was MRSR, and that there was an epidemic in the US. They had to do four incisions, and it hurt like a SOB. I wanted to punch the Dr. in the face it hurt so bad, and I have a high pain threshold. Just a heads up, keep an eye on anything that starts out as a red bump, if it starts getting painful, get it looked at. It's not a fun experience.
