Stop smoking. Get a USG neck done

If u feel that there is a lower neck swelling which is persisting you need to consult a physician and get an ultrasound and chest x ray done. It can be inflammatory swelling and can take a course of antibiotics and see if its subsiding.

It would be better to do an USG and see if any sonological features of malignancy is there in the node. Also can see if other nodes are there in any of the other neck node stations. Consider doing blood tests like complete blood count, LDH, uric acid , electrolytes. Also see if you have any other relevant symptoms which you should notify treating doctor. Based on the USG findings, can decide if an FNA or biopsy would be apt. Also there is possibility that this could just be an infective node. Anyway let the USG happen.

Hi. Although enlarged lymph nodes can be due to multiple causes, it is important that you get it evaluated by a physician. Clinical examination is also necessary apart from ultrasound. Also cessation of smoking is important.
