I dont know if this is a really dumb question or not but i decided to ask anyway. I came down with a upper resipatory infection, a couple days prior my fatique was worse than normal and then i started not feeling well. Since i have had this little cold and it is little my chest muscle ache like pulled muscles which doctor said is normal with fibro. And my muscle fatigued is worse then normal which makes them a achy, like flu achy. Does anyone else feel like this when they are sick
