fatigue/recurrant illness's/cold's

I am over on year out and that past four months I have had terrible fatigue with recurrant sinus infections/cold's and feel terrible.  Anyone else experience this and what did you do to correct it? I have been to the dr three times since the new year and all labs are fine.

Have u been to an ENT yet? If not GO! They can take care of recurrent sinusitis better than a PCP. I have issues with by sinuses and allergies and have to stay on an antihistamine/decongestant. Good luck!
