[|Human|] Hello, I am a 48 yr old female. I have had swollen lymph nodes on the left side of my neck twice now. First I had them 3 mos ago and the soreness went away.  Now the swelling and tenderness is back.  I went to a clinic and the Dr. put me on Bactrim after 3 days swelling still there.  Now I went back to a different Dr. at the clinic and he put Cipro and ordered a CAT Scan.  Why do you think the lymph nodes enlargement and tenderness comes and goes?
[|AI|]  Welcome to Chat Doctor .1. Lymph nodal enlargement is because of inflammation / infections (Tuberculosis, high grade fever, breast inflammation) and seen in the underlying malignancies (different cancers) 2. So need to find out the cause and treat.3. An biopsy of the lymph node will give the cause.4. A CAT scan definitely gives possible diagnosis.5. Hope it helps you. Wish you good health. Anything to ask ? Do not hesitate. Thank you.
