Hi, My boyfriend started off, with a small white head, with a large red ring around it. Our first reaction was to try and squeeze the pimple. When we soon realized that it was definitely not a pimple, we went to the nearest walk-in center. He then was diagnosed, mind you..(The physician did not do a culture), with having a spider bite. But, I have been observing him these last three days, and its getting more swollen and his discomfort has worsened. Its even difficult for him to walk. And, I just now found out, that he has been diagnosed and hospitalized for having MRSA , 10 years ago. It is not looking good. should we go to the ER?
