Last Year I Got What Appeared To Be Boils On

Last year I got what appeared to be boils on my buttocks when I showered some of them would have hard white pustules come out of them. The doctor gave me Mupirocin cream to apply it did not really help as the rash never totally went away. Over the last month I have been getting what look boils or fatty deposits on my trunk arms and legs that don't hurt, some may itch, not all. Now they are appearing on my head and face, those hurt and I am having horrible headaches. I am going to call my doctor on Monday. Any thoughts would be appreciated.
