Admittedly Im a hypochondriac. On March 28th I met a girl while on vacation and we hooked up, we didn't fully have sex but we did oral. Two weeks after that I had mild flu symptoms, no fever, but a headache, muscle pain, a chest cough, but mainly bad congestion. I was prescribed Tamiflu and within the fifth day of taking it my symptoms were gone. I had a flu shot but my doctor said it was still very possible to get the flu with the shot. Im pretty sure I'm just over reacting, as a few of my friends just had the flu as well, but once I had this idea in my head it just kinda festered.
