Hi,
I am feeling exactly like you, I am trying my best to stick it out till I go home. Went to the doctors today, they just said it was a bladder infection, gave me antibiotics. I think it's something more, I have the chills with it. I do also experience the flu like feeling, but this is different, something is going on. I also have pain in my lower right backside.
Don't just dismiss it, please contact your doctor so they can rule everything out.
I'm actually feeling scared right now because I wonder if I got bit by another infected tick? (Lyme) Hang in there!!!
