I believe I have a cold, runny/stuffy nose and headache and sore throat but my jaw is aching and my teeth in the back near my jaw. Is this normal?!?!
Cold. Your cold is effecting your sinuses which can put pressure on the upper molar teeth and make them sore. What you are experiencing is common and will resolve itself as your cold gets better.
Sinus and tooth pain. Sinus pressure can cause pain that is felt in the upper rear teeth. As the cold and stuffy nose clear, the tooth pain should go away. If it doesn't go away, it would be reasonable to see a dentist. http://www.mayoclinic.org/diseases-conditions/acute-sinusitis/expert-answers/toothache/faq-20058299.
Sinus maybe. Hard to say without a history and exam. I would get to a Dr. and be checked.
