My throat kinda hurts when I swallow my saliva, and I have a runny nose, sneezing, watery eyes. What happened?

Consult Eye MD. If persistent red eyes, new onset blurred vision, or excessive tearing...Then consult eye md to evaluate for possible dry eye syndrome, glaucoma, tear drainage system blockage, or other ocular allergies, infections, or inflammations versus simple viral conjunctivitis associated with viral upper respiratory infection.
URI or Allergy. You probably have an upper respiratory tract infection (URI) or allergy. You possibly have a "strep throat" and should consult your primary care physician.
