My brother had what he thought was a spider bite a few months ago. He went to the doctor who prescribed an antibiotic. He didn't have it filled and it finally healed on it's own. Now his legs are reddened and swollen with what was diagnosed as cellulitis. I am really concerned as he is a diabetic, and so is my elderly mom who he spends a lot of time with. I am just beside myself! Many of my friends have seen a pic I posted of the "spider bite" and said it was MRSA! What can I do to get him to see another doctor?
