[|Human|] 18 year old girl with symptoms of tmj. 3 years ago had a large 3 &1/2 inch by 1 & 1/2 inch epidermal inclusion cyst removed from in and around rt ear canal and told it might grow back because it was removed in parts. So dr performed a ct scan of neck. Rt side is good, but an elated 1.3 cm lymph node was seen on left side. Dr wants to follow up with a sonogram in 2 weeks. Should I be concerned?
[|AI|]  Hello, I can understand your concern. As you had developed a cyst on the right side, it is possible that you might have developed the same type of cyst on the left side which may cause similar symptoms as you experienced on the right side. Alternatively, the condition can be unrelated, and the lymph node might be enlarged just because of bacterial infection that it may have acquired. Usually, such swellings are treated with antibiotics first as bacterial infection can be the first assumption. However, your doctor is advising a sonogram because of your history of a cyst on the other side. At this stage, I can help you with this little information that if the swelling is painful, it could be infection and in case of absence of pain, chances of a cyst are more. I would advise you not to worry about the situation as in any case, the condition is not severe and can be treated with medicines or small surgical procedure. I hope this information helps you. Thank you for choosing Chat Doctor. Let me know if you have follow-up questions. Best,
