Doctor can check: Throat pain can be from a strep throat infection (antibiotics are needed), a cold, influenza or adenovirus (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor if the symptoms are bothersome, recurrent or doesn't go away quickly (mainly to check for strep throat). With cold symptoms and eye discharge, one is likely contagious.
