I seemed to have gotten a sinus infection that began on the first day of a really bad cold on New Years eve. Green mucous and everything. I went to the doctor and he gave me Keflex for Antibiotic and here it is 6 days later, my nose is still green as ever . The last time I had these pills it cleared up within a few days. I have horrible pain throughout my head. I have to blow my nose like every 3 minutues and I swear my other nostril is fused shut, it hasn't worked since I got sick. Everymorning I wake up and everything is still green if not greener then the morning befor. I need some sort of relief. Can anyone else offer some advice on wht to do? it would be great. I hate this with a passion.
