Ugh. This sounds like no fun at all. Sorry you are having one of those weeks.
I have been through this before and finally decided to find a family doctor who could see all of us. We've had some excellent ones over the years. For illnesses like colds, flu, pinkeye... it's easier for everyone to go in to the doctor together when we are all sick. Or, if one person is sick and others come down with it, the doctor can prescribe the pinkeye med for example over the phone for each individual as we catch it. My family also has alot of allergies, so it helps with medical history if the doctor knows what runs in the family. Anyway, after years of dealing with ob's, internists and pediatricians, having one dr. to oversee our general health has saved me alot of time and trouble.
Good luck, hope you are all well soon.
