Sinus infections, there was another recent study, stating that antibiotics did not have a significant impact on the treatment of sinus infections as the medication had trouble reaching the nasal cavities.
Discharge of cloudy or colored mucus is usually indicative of sinus infections and hence treating the symption with a medication that usually does not work on the illness not working is not a huge suprise to me.
You need the right med for a sinus infection..Keflex (sp??) worked best for me. It knocked it out...bam bam...
