I woke up with a slightly stuffy nose and my left eyelid a bit swollen and sore. am i coming down with something?

Probably: you must be examined and treated today. Call for an appointment.

Stuff nose, puff eye: Sleep with the head of bed elevated Likely have nasal congestion/allergy and during the night the fluid runs down into the eye area due to gravity, elevating head of bed avoids this Reflux can also cause this by irritating the nose with acid. Consider benedryl before bed x 2 weeks, elevating HOB and prevacid for reflux f/u with doc

Snifful/congestion: The same virus that causes a cold, can get in the eye, and cause a form of "pink eye". Get rest, vitamin C, and fluids. In the mean time, wash the affected side of your face after the non affected and with a different cloth. Both should clear in 5-7 days. if not, see your doctor
