Doctor gave me the thumbs up. Spider bites should heal on their own. No skin graphs or specialty doctors. He was very impressed with my progress, and I even told him I did some dancing over the weekend (and no swelling). It will be a few more weeks for healing, buying a semi truck load of gauze and roll gauze, but it will heal. I will have a nasty scar, but I am very happy. I really like my new doctor too. Once again, nurses came to see the updated larger bite, ha ha! I'm like a hot topic there when I arrive. Trust me, if you saw a photo of what it looked like when I first went to the second doctor, you'd be "sweatin' bullets" too. He and I both were concerned.
The heat is drawing the spiders into the house and I have yet to spray inside. As they crawl in to escape the heat, however, the outside spraying should keep them from living too long if they do get all the way in. I had to swat at jumping spiders all yesterday afternoon.
