Natural Remedies for a Brown Recluse Spider Bite

We had been home treating 2 Brown Recluse bites my husband got on his shins for 10 days or so. One had become very purple/red and his leg/foot was swelling and about a 2 inch square of flesh around the 'crater' of the bite looked like raw hamburger/open wound that continued to leak clear/yellow fluid. I found a website about spider bites that mentioned a man's story who had been bitten numerous times over the years by recluses, he had finally ran into a vet that gave him 3 small injections with a tiny needle around the 'crater' of the bite with cortisone. He said it started healing immediately. I printed this out and took it with us to the hospital. The ER doc said there was not much he could do for it, that it would get worse looking before it got better, that the swelling/inflammation was not allowing the blood to flow to the wound, so the flesh was dying. He prescribed antibiotics. After he had finished with his diagnosis, I pulled out the pages I printed and asked him about giving my husband the cortisone (Dexamethasone) shots that the article spoke of, since there was nothing else he knew to do. He flatly refused and wouldn't even look over the article. VERY frustrating! We left and came home to sleep til the pharmacy opened next am. Before bed as I was dressing the wound again, my husband recalled that our Dr. had a while back prescribed some cortisone cream for a rash he had on his hand. Figuring it couldn't hurt, I cleaned the wound as usual with apple cider vinegar (it helps keep the skin alkaline, preventing the acidic environment needed for infection to proliferate) then applied the cortisone cream around the open wound, but NOT on it, and bandaged lightly as the wound was still oozing. We woke up several hours later to find most all the swelling was gone from his lower leg/ankle and the surrounding area that had been so purple/red had faded considerably. The Dr. told us the flesh around the wound was dying, and would fall off, due to the inflammation not allowing the blood to flow and regenerate the wound to heal. BUT, after applying the cream for the last 4 days, the swelling has gone down, and the wound formed a scab that fell off naturally to reveal new, pink skin underneath. The original "crater" of the bite is filling in and closing up quickly. I thought that perhaps if someone else runs into a stubborn Dr that refuses to give the cortisone shots, our experience might help them as well. The name of the cream we used was Betamethasone Dipropionate 0.05%. It was prescription, but I would think that any cortisone cream would have some healing effects to allow the swelling to go down and the blood to flow to the would to facilitate healing. This is the 4th time he has been bitten here in Oklahoma, if there is a next time we will be sure to take a Benadryl and apply cortisone cream ASAP! We never did get the antibiotics Rx filled (he gave us 2 kinds- one was Clindamycin, no way was he taking that! ), I applied iodine to the open part of the wound twice a day, I read on Earthclinic that it was used for infections before antibiotics were discovered, and it has healed much quicker than before I was applying it. I hope perhaps this will help someone else who has a bad spider bite.
