<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi - First of all - I am a 36 year old female, 59, 260 lbs. I have a history of Lupus, Occipital Neuralgia, degenerative disc disease. I had occipital nerve blocks on both sides of my head about two weeks ago at my new Neurologist. Immediately following and for two days, I had pain at the injection sites. My right side has always been affected worse than the left. When my nerve is irritated I get pain and swelling in the occipital area, double vision, and swollen lymph nodes. Anyway - now - two weeks later - there is pain and swelling where the injection was on the right side and the lymph node is swollen again. Have you heard of this happening? Should I be immediately concerned? Thank you.  <response>: Hi, thanks for writing to Chat Doctor. Based on your description, I suspect that your symptoms could be possibly due to an infection at the injection site leading to pain and swollen lymph nodes Chat Doctor. Use of an appropriate antibiotic for a few days along with anti-inflammatory medications may be helpful in resolving your issue. Consult your treating doctor a detailed clinical examination and further evaluation, if necessary. Hope this information is helpful. Good day
