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 wether 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.
