Hi Dr. Oana I am a throat cancer survivor and 2 weeks ago I started out with a swollen neck fever feeling like the flu symptoms I now have a rash on chest and back that started spreading to my face and can barely swallow.  I am 60 year old male and been cancer free for 20 months so far.  I am in the hospital and the doctors are baffled.
Hello;Your symptoms suggest that you have some acute problem rather than recurrence. Have you undergone blood test, chest x-ray and cultures to see if you have any infection or not. A endoscopic examination of head & neck and/or CT scan of neck can tell whether you have recurrence or not. In patient who have recurrence in neck they usually have swollen lymph node in neck. But getting fever and rash at recurrence is not common. Regards
