Hello, What you describe is a boil. I get them too. I get them during the hot months more than the winter. They are hard like large pimples and painful. If you try to squeeze them they can bust and drain, but I dont recommend it because it will make them hurt more. See a doctor and he will give you some cream and antibiotics. But.....Be prepared to get them again. Sometimes they bust on their own. I get them between my buttocks. I let them drain naturally and when they become uncomfortable, I place cotton between my buttocks to cushion it while I drive. I hope this helps..........Bye
