[|Human|] Hi, My baby is 4months and 8 days old.She had fever last week for which her doctor prescribed calpol drops and an antibiotic.The fever reduced and she was fine. 3 days back she had cold for which we gave her coltrec. yesterday we noticed slight swelling behind her right ear.We visited her doc again he told us that it may be a infection and prescribed calpol and an antibiotic. She has her milk properly she is cheerful as usual.But I am worried about the swelling please advice
[|AI|]  According to the shape and size of the swelling we can determine .mist probably it is an enlarged lymph node which looks like small regular surface mass, could be mild painful with touch .but don't worry with it because it is a reaction from the immune system toward any infection. But if the swelling is not of regular surface, red or hot, it could be mastitis (inflammation in the mastoid bone behind the ear due to in appropriate management of upper respiratory tract infections .in this case, you will need to revisit your doctor to further assess and may need surgical procedure
