Ive woken up w sore throat/bad chest.can i still go to gym & workout?or will this make me sicker?i feel fine other than chest/throat.ive had flu shot

Hard to guess: Throat pain can be from strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, one sees a doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to see about antibiotics). Lots of coughing makes it less likely to be strep throat. Best to rest a few days.
