Him I am on my 3rd day of argmentin, for nose cellulitis, and I am feeling worse than before. My nose is more swollen and painful, and the inside wall of my nostril is very swollen, it cold be developing pus? Also, my upper lip where it's right under my nostril is harden, could the infection be spreading? Is this normal for augmenting treatment or am I not responding to the drug? Should I finish the 5 day treatment first or See the doc right away?
