When you have a lymph node that is swollen about the size of a 50 cent piece on the side of your neck and your neck hurts and it hurts to swallow I am assuming that you are fighting off an infection.   Question is:  When you are an asthmatic and are prone to blood infections should this be a concern.
Hi, As you are having swollen lymph node in the neck it indicates there is some infection in surrounding area like scalp, ears, throat. As you are prone to blood infection and likely of precipitating asthmatic attach, it requires treatment with antibiotic medicine. Consult your doctor and get examined. Ok and take care.
