I have a dry cough and slept a lot of the day. have felt a little fluish. no sore throat though but worried about my chest?

Keep an eye!!: If you are otherwise a healthy 49 years old, a dry cough, some tiredness and feeling hot, is worth keeping an eye on your temperature. A cough medication might help but if you have a fever or symptoms progress, is worth calling or doing a video consult for consideration of testing for Covid 19. You may want to check the availability of testing and requirements in your town.
