One of the 200+ virus strains implicated in the cause of the common cold have infiltrated my system. So I ran out to the pharmacist on Wednesday night. Help! I said, I need something that will make my nose stop running and sneezing, but still leave my sinuses clear so that I can fly on Thursday. He gave me an antihistamine, which seemed to help. I don’t have a fever, so it’s probably not the flu. I read on line that one can actually have the flu and not run a fever!
