Itchy and very sore throat, eye pressure, nose stuffed up or running like crazy, ears extremely clogged with occasional stabbing pains. Please help?

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). With bad symptoms, one may have ears and sinus infection (antibiotics needed).
Allergy or Sinusitis. This sounds like a very bad allergy that has turned into a sinus infection. Probably needs to be treated with a combination of antihistamines, decongestants, and antibiotics. Consult your family doctor or internist first, or an ENT specialist if you have one.
