I got nailed once on the back of my leg. Went to the doctor the next day. Shots and pills and still had a hole the size of a golf ball. If you haven't yet, get to the doctor. It won't go away on it's own.
expect some major swelling and permanent scarring. if your immune system is weakened at all dont play around..Might be advisable to take a few weeks off work while it heals..
I was bitten on the eye lid two years ago and still feel the affects. Doctor thought that I was going to lose my eye but he saved it. It was really, really ugly for awhile and lost the eye lid but it grew back. It is a must to see the Doctor. There is an outbreak of Brown Recluse spiders this year due to lack of cold weather last winter. Be careful and take care.
