question: i had a FESS in july 2010 and been ill with yellow mucous from nose, pain in face, left eye throbs, and been on constant antibiotics over the past 7 months, a ct scan said i had disease of the left ethmoid before surgery, i had post nasal drip for a month and i am still now coughhing up yellow phlegm. i have seen the hospital registra over the past 2 months but now feel the antibiotics are not working, seen my gp today given augmentin, stopped the clarithromycin that i should be on 6 weeks, is there any other way of finding out my problems?
