Hello.
About a week ago I got a little sick with a stuffed nose, sore throat, cough. I stayed home for 5 days, treated it and it got better. However, yesterday I went outside for the first time in 5 days and today I woke up with stuffed nose. And when I got up and moved myself, I felt that the right side of my neck was painful. When I don't move it, I can't feel the pain, but when I turn my head hurts a lot. What could cause this?
Thanks in advance.
