I have had swollen glands for over 7 weeks after possible Strep throat...was treated for Strep but pain in left Lymph Node still swollen with mild pain, increasing size and pain after lying down. No pain or swelling on right side just the left side with effects on the left ear and headaches.
Thanks for posting your query to Chat Doctor. As I understand it could be due to some remaining infection.  I suggest you to consult a ENT surgeon and undergo proper examination. You can take painkiller like Aceclophenac with serratiopeptidase for symptomatic relief .hope it will help you.
