Hi, I had gone through your question and understand your concerns. Considering your description there is a reactively swollen neck lymph node which is commonly seen as a reaction on any infection in your body. Also, this may be benign lymph node growth such as lymphangioma. It is good that you have done tests Ct scan to rule out malignancy but I am not sure if you did ultrasound guided needle biopsy to verify exact pathology. I suggest to do this and if this is negative then you should consider surgical removal of the lymph node since if this presses surrounding tissue or causes discomfort then this is symptomatic and treatment is indicated even if this was not a malignancy. Medicamentous treatment can be tried with antibiotics but only if infectious cause is established. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
