<human>: My fiance woke up this morning with a pain on the right side of his neck. He first thought he slept wrong, then realized there is what appears to be a vein behind his right ear that is swollen. Pain goes down his neck and up the side of his head. Is this something to be concerned about?
<bot>: Hi, If he does not have fever and there is no local redness of overlying skin, we need not worry now. There is a normal prominence behind our ear-this is formed by mastoid bone and tendons attached on that. If he is able to feel a similar swelling on the opposite side also, probably he is dealing with this. Just ask him to take paracetamol three time as a day(ibuprofen if pain is severe) for 3 days. Hopefully pain will disappear by then. Otherwise, kindly see a doctor to look for any local infection or lymphadenitis. Hope I have answered your question. Let me know if I can assist you further.
