I have had a very sore throat with swollen lymph node on right side for weeks and lately hurts especially after talking more than a few sentences even after I've gotten it to calm down with nsaids, ice chips, etc. An antibiotic was given previously and didn't help, now taking small course of prednisone which seemed to help till I talked to much, a doctor had ordered a ct or my neck. I have a history of severe constipation and currently have an inguinal hernia. My question is, what would be the most appropriate and safest test to diagnose my throat issues...ct, barium swallow, mri or other. Thank you.
