Roller Coaster Body Temp

I have been pretty sick the last few days. I think it's only a cold but who knows? I have been running a mild fever. Last night it was 99.9. Then when I woke up today I felt a lot better and my temp was down to 95.5. After I tried to go for my daily walk at Walmart I started to feel a lot worse and my temp is back up. 99.4. Not too bad but I do notice the difference. 
I have been coughing and gagging all day. (I know...poor baby. I'm such a wimp!) Oh well, no more walks for awhile.
