Are you stubborn for a doctor’s check-up?
If your stiff neck is accompanied by chills and a fever, then, call your medical practitioner immediately and set up an appointment. Or better yet, go to a walk-in clinic near your neighborhood and have that condition of yours assessed immediately.
This is no joking matter and it must be addressed to as soon as possible. It could be a serious health condition and it is better to know the necessary treatment before it gets worse.
