Hi, a few days ago (saturday) I squeezed a pimple on my cheek and felt it pop, but underneath the skin (I know, I should have known better). Sunday the pimple was redder, but about the same size. Sunday night some pus oozed out. I woke up this morning and there was a hard lump near the pimple under the skin, my cheek is moderately swollen and painful. It seems like I have ruptured the pimple and maybe the pus is now in the surrounding tissue, causing it to be hard and swollen. What should I do?
