Is it normal to have a swollen lymph node for 6 months? Hi, I am a 20 years old female. I have had a painless lump or swollen lymph node that has been in my neck for six 6 months now since December 2010 that can only be felt, but not seen. The lymph node is no bigger than the size of a half a dime and feels like a swollen kidney bean that keeps changing in size from small to big and then smaller again, but it never fully goes away. In terms of texture I cant tell if its firm, soft or hard. Its hard to tell. Anyway, I finally went to my doctor in early April 2011 to get it checked out and he put me on a weeks worth of antibiotics, and prescribed me some allergy and asthma medication. He also did a chest X-ray and blood test that came back normal. When I went back to my doctor he said that the lymph node had shrunk and that was a good sign and that it might have really been an infection. So he told me to observe it for a month and come back to check it out and if its still there he will send me for a biopsy. So far the lymph node is STILL there and it feels like it enlarged back a little, but that might be because I keep picking at it from worrying so much. So far I dont have any symptoms of fevers, night sweats, fatigue, persistent itching, or unexplained weight loss, in fact I gained ALOT of weight from anxiety and stress eating from the fear of this being lymphoma or some other cancer. Lastly, I think its in the posterior triangle area of my neck not sure of diagram of lymph nodes. Is it normal for a lymph node to be swollen for 6 months?

Thanks for your query at Chat Doctor. I understand your concern and situation. You are having chronic lymphadenitis. Lymphadenitis occurs when the glands become enlarged by swelling (inflammation), often in response to bacteria, viruses, or fungi. The swollen glands are usually found near the site of an infection, tumor, or inflammation. Prompt treatment with antibiotics usually leads to a complete recovery. It may take weeks, or even months, for swelling to disappear. Sometimes it is seen that lymph nodes respond to treatment but with recurring throat infection there is changing sizes. You can get evaluation done by ultrasound guided FNAC or biopsy for AFB, culture sensitivity test for aerobic and anaerobic bacteria, cytology. This will clear your doubts. Take care.
