In the past two or three years I have had approximately 4 large round hard sores on my left buttock, it does not seem to have puse in it as a boil does, it burns and itches and after a few days it seems to start drying up and goes away---the first time was during a time that I had taken diet pills, and I thought they caused it, in fact every time that I have had them I have taken some type prescription med or a different vitamin. The last one that I had was after I had taken a week's worth of cinnamon capsules. I don't know that the meds cause it or why but it seems likely and I need to know why--
