[|Human|] Hi I had a mosquito bite around 1 month ago on my mastiod bone behind my left ear. Now the itchiness and the redness has gone but a week ago I was feeling behind my ear and noticed that my left mastiod bone is much bonier and protruding than my right mastiod bone. After further inspection I also noticed a hard lump that feels like extra bone on my mastiod bone, aroundabouts where I had my mosquito bite. I was wondering if they are related?
[|AI|]  Hello, Welcome to Chat Doctor, The symptoms of swelling behind the ears following a mosquito bite and the swelling has persisted for more than a month. The swelling following the mosquito bite will not last for this long period. You require physical examination to find out the reason for the swelling, and then we can suggest an appropriate mode of treatment. There are many conditions which can leads to this problem. It may be due to infection of the mastoid process and the middle ear. I would suggest you to consult your ENT surgeon for further evaluation and treatment. Thank you.
