After a breakout of a cyst like spot on my lip, I have been left with a hard pump under the skin thats red in colour. The cyst was painful to begin with and caused a lot of swelling across my top lip but after draining Its painless but annoying to still have such a bumpafter the breakout cleared up. Any advice on why this pump is still here? Or how can I drain/get rid of this hard pimple?
