I have reaccurring infected spots appearing on the one forearm.  They start off like a pimple and then over 24 hours become very red and swollen to the size of about 10com across and very sore.  At first, it was thought it was a spider bite - but it is happening on the same arm around the same place.  They ooze pus become quite open and a core occurs.  They have been treated with antibiotics, but now
