Why does my back hurt if I'm sick with a cold?
When we get sick, it's not unusual to have aches and pains. Your back could be hurting from coughing and sneezing. It could also be feeling achy if you've been laying down a lot.
I have bronchitis- not only does my back hurt but also my front, sides and everywhere else from all the coughing in the past 3 weeks.
It could be a kidney infection also.
