Prayers up, you will need them, I have seen this before. It takes a month or longer to heal. My wife got one on the back of her thigh. After the doc cut the bad flesh out, you could have put a golf ball in it. Severe fever and nausea was some of the side effects. I was a long month for her. I had to change the packing in it each day, and it started out with an eight foot strip. Nasty!
