I have what seems to be an enlarged lymph node in the back of my neck, where back, shoulder and neck meet. Not really big, I dont think its bigger than 1 cm, 1.5 cm at most, but pretty hard. It pops out more when my back is tender. Its been there for almost a year, I went to my doctor when I found it and he said it was nothing, blood work was ok. But its still there. Should I concern?  <response>: Dear Friend. Welcome to Chat Doctor. I am Chat Doctor. I have read your query in detail. Furthermore, I understand your concern. The lymph node can be due to bacterial infection if it is single. In such conditions, I advise following:To take antibiotic like Augmenting for a week. If the lymph nodes settle, its good. If it doesnt then a FNAC would be required. So, you may observe this and after 1 week, if it doesnt settle, get following:1. FNAC of the Lymph Node2. ESR3. X-ray Chest4. Sputum For This is my best advise for you based on available details. If you have any further query please ask me. Stay Healthy. ChatDoctor, MD
