Two wisdom tooth removed at a time.lymphnodes below ear remain swollen for three months after antibiotic treatment.is it required to remove lymphnode?

No Lymph Node Remova: You definitely want to go back and see the dentist, or oral surgeon that did the extractions, there could be complications in your case. Since i cannot physically see you, i cannot be sure, but your symptoms require a post-operative consultation with the surgeon. Most remedies to such issues are fairly simple, but equally necessary. Best of luck to you!

Lymph Nodes: Many people have chronically swollen lymph nodes or at least palpable ones. It may or may not be related to the wisdom teeth that you had removed. Regardless, you should be evaluated by an oral surgeon and possibly be referred to your physician to determine whether or not further investigation or treatment would be appropriate.

Second opinion: I would recommend pursuing other treatment options or opinions.
