From the time I was 12 until the time I was 17, I had frequent chest infections. I had pneumonia a few times and bronchitis a few times too, I would get seriously ill maybe twice or three times a year. Since I was 16 (almost 20 now) I have had a somewhat swollen gland under the right side of my jaw, not big enough to be visible but bigger than the other one on the other side of my jaw. I also have a history of environmental allergies. No cancer like symptoms, just wondering if I should do anything about it. I was wondering if lymph nodes can scar and become permanently larger due to frequent infection? Or if allergies can cause swollen glands? Also if a gland can just be larger than normal but not dangerous?
Thanks,
a.
