I've been diagnosed to have sinusitis one month back. I started using a course of cephalosporin, trypsin,levocitrizine for 5 days I was unable to use the antibiotics in the last days. I was given nasal drops which I use only when I have blocked nose. Ive reduced eating curd and icecream though I still eat icecream once in a week and curd thrice a week. Recently I started having headache again and today I started having post nasal drips and a feeling of spasm in throat with some cough due to irritation in throat. Would you suggest me to undergo the same medication? I won't be able to reach the doctor for a week.
