I m 46 years old, I have been getting sick to often. A year ago I had pneumonia for about 3 months, a couple months ago bronchitis, now I noticed swelling between my neck and collarbone to my right side. Dr says xray of lungs is clear that it may be an infection and started me on antibiotics, now i feel my throat glands hurting and what feels like the oncoming of a sore throat. Im also feeling upper back pain and headaches. Should I worry....
