MY FATHER 84 YRS OLD FELL A NUMBER OF YEARS AGO AND BROKE THE LEFT SIDE OF HIS NOSE,  SURGERY TO REPLACE CARTLIDGE WAS DONE.  AFTER TWO YEARS OF SURGERY  NOT MUCH RELIEF  AND DIFFICULTY BREATHING, WE TOOK HIM TO A ENT/PLASTIC SURGEON.  ANOTHER SURGERY WAS DONE AS THE FIRST CARTLIDGE DID NOT TAKE SO MORE CARTLIDGE WAS REPLACED.  SINCE THEN, BREATHING HAS IMPROVED, HOWEVER, AFTER APPROX 2 YEARS HE IS COMPLAINING OF PRESSURE FROM THE LEFT SIDE OF HIS FACE TO TOP OF HEAD AND RINGING IN THE HEAD INTENSE.  RECENTLY, BEEN DX WITH SINUITIS.  IS IT POSSIBLE THAT MRSA MAY BE IN THE SINUS CAVITY AND COULD CAUSE THESE SYMPTOMS?
If the cause of sinusitis is some sort of acute infection causing increased trouble it can be a bacterial infection such as MRSA or even others also. Better to test for infections if needed
