hey, i was developing these hard pus filled lumps on my body, some were small, some would grow about dime sized before they would pop on their own. after the 4th one i got worried so i went to the doctor, he didn t really tell me anything, he popped it and took a swab and then gave me a prescription for clindamycin. i would just like to know what exactly is the infection i have? what is this medicine typically prescribed for
