What causes a large bump behind the neck while treating a tooth infection?
Patient: I was prescribed 500mg amoxicillin two weeks ago for a tooth infection. The infection is not gone and rather there's a large bump on the back of my neck- I think from the lymph node, my lymph nodes behind my ear are swollen, I'm light headed, and my skin feels horribly itchy. What should I do Doctor: Hi.Welcome to HEALTHCARE MAGIC..I have gone through your query and can understand your concerns..As per your complain tooth infection does not commonly completely subside with only medication that is antibiotics and painkillers and need proper treatment of the tooth itself for complete resolution..As far as lump on neck is concerned it can be swollen lymph nodes secondary to infection..Lightheadedness and itchy skin however does not seems to be due to tooth infection, rather they are signs of allergic reaction that can also be due to medication that you are taking..Consult an Oral Physician or an Endodontist and get evaluated and a thorough clinical evaluation and investigations like x ray can help in diagnosis and treatment can be done accordingly..If tooth can be saved root canal treatment can be advised while if there is gross decay tooth might need removal..For itchy skin take levocetrizine and if still not resolved consult a General Physician and get evaluated..Hope this information helps..Thanks and regards.Dr.Honey Nandwani Arora..
