Hi, Dr. I Have A Sore Throat And Congestion In

Hi, Dr. I have a sore throat and congestion in my head. This started Saturday morning. I did not go to work on Monday. I felt better this morning so I decided to go to work. Looks like I have pink eye. My eye itched some doing the night but I didn't think anything of it. My right eye is very red, and keeps getting mucus or something on my eye lids and the eye is achy,
Can I use an over the counter medicine or do I need to go to the doctor.
