PLEASE PLEASE READ AND HELP ME OUT, IDK WHAT'S GOING ON AND IT'S SCARING ME

I'm not sure really how to explain this or anything but a few days ago i noticed i was having pains on the left side of my neck below my ear, i figured maybe i slept wrong until the pain got worse and i started having involuntary head movements. the head movements aren't severe or anything but i asked my husband last night if my head was shaking he said it was. so it shakes and if i am sitting straight up i noticed my head twitches a little bit, and when i put pressure on the site of the pain the right side of my head starts hurting and brings tears to my eyes. It's kinda odd. I'm not sure what to do or what's going on. I don't have health insurance right now so i can't go to my doctor's office and i can't afford a hospital bill either. I'm kinda scared about this. I've never had anything like this before. Does anyone know what it could be???
