I don't have insurance nor do I have money to see a doctor. I have had severe neck pain for several days now that is getting worse. It is causing headaches and blurry vision. I'm very tired because I don't sleep well due to the pain. Should I go to the ER or just bear the pain no matter how bad it gets?

What is your life worth to you?

There are a number of resources at the top of the Medical conditions forum that can help if you don't have insurance. Finding a way to the ER or a urgent care would be good for you. It could be a pinched nerve or muscle strain, or it could be something much, much worse.
