These "pimples" are getting could be boils...Yes boils. I get them every once in awhile. Sometimes they can be very painful. They are sometimes, but not always caused by staf infection( which is very contagious). I would go to a doctor to get them checked out. My sister had staf infection and that led to an infection inside her hip bone and her hip is parralized(never go back to normal function). If its not that at least u can put ur mind to ease.
