I have a chest infection or maybe bronchitis and i want to know do i have to stay in bed the whole day or can i go out and leave the house and go out.

?fever: If you're not running a fever, having chills, sweats, significant wheezing or shortness of breath you don't have to be housebound while on treatment for bronchitis. Avoid crowds, excessively hot or cold places.And pollution, .

Depends: If you are having difficulty breathing you can go outside but limit the distance from assistance if you require it. Otherwise you should be fine to go out and relax. Hope you are better soon and that you stop smoking.
