What causes a sting sensation in a cyst on the back of the neck?
Patient: I have a cyst on the back of my neck that was drained a few months ago.  Started getting a sting sensation yesterday. What does it mean? I am supposed to have it surgically removed but can't afford it right now (it swelled up to the size of a golf ball before the drainage and took over a month to stop draining!). Doctor: Hello,The sting sensation could be related to an infection. For this reason, if it hurts when touching or the stinging persists, I would recommend consulting with your general physician for a physical exam and some tests (complete blood count, PCR) for inflammation. You may need to drain it again if its dimensions increase. Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Aida Quka
