I've been experiencing a cold, especially morning hours but recently my headaches have been nonstop plus i remove pink phlegm accompanied by some throat thus swallowing food is painful i get fevers & sudden chest &back pains, what could be the issue?

Doctor can evaluate: New throat pain can be from a strep throat infection (antibiotics needed), a cold or mild flu (antibiotics are not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor if the sore throat is bothersome, recurrent, or doesn't go away in a day or two (mainly to check for strep throat). Doctor can also check for chest and back pain reasons.
