Q. Dear Dr, I was surgically operated on for the dis-impaction of my lower third molar on tue the 17th Its day 5 after my surgery but I still feel pains without the help of a pain killer.I may also have to get a stronger pain killer cos I no longer get so much relief from Cataflam which I have been taking. Also what worries me is that my lips is still numb and feels swollen after 5 days of the surgeory,,this causes me so much discomfort.How long would this last for? I also have a sore on my lip,it hurts when I rinse with the warm water solution.can I apply zovirax cold sore cream on it?,
