I've been sick the past few days and its not getting any better, I have a sore throat, stuffy nose, a slite fever, body aches, cough, and now my jaw hurts towards the back like I need to bite something. Could my jaw hurting be related to me being sick if so what could it be?

There are many things this could be. The only way to get an accurate diagnosis and the proper treatment is to see your doctor.

No one on this site, or any other, can give you a diagnosis over the internet.

It could be a cold, flu, strep throat, or more.

Get yourself to a doctor for a proper diagnosis and treatment.

You could have a cold, or the flu. I'd go to the clinic and get checked. Maybe a round of antibiotics will help clear it up. Good luck and I hope you get to feeling better.
