<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing a lot of pain and swelling in my lymph nodes. I have a hard time moving my neck and it hurts to swallow. What could be the issue?  <response>: It sounds like you may have lymphadenitis. To confirm the diagnosis, we will need to run several medical tests including a hematologic test, a complete blood count, a CT scan, and a urinalysis. We will also need to check your kidney function, electrolytes panel, and start you on intravenous fluid replacement therapy.
