I was bitten by some type of spider during the night, its been just over 4 months since the bite, the first couple of months it didn t see to bad and actually looked like it was getting better , as they time went by it slowing started getting worse, now it is really red and around the bite and very painfully ,the bite it self has turned in to a sore that it looks like hole ,I also stepped on a nail in my sisters yard a couple months back and was wondering if by chance by stepping on the nail would have had anything to do with it getting worse?
