Should I go to er?

So I have no health insurance but get bad migraines and today it’s to the point I can’t move or see really well. My dad passed from a stroke and my grandfather also had a stroke. I know without health insurance the only option is the ER as a regular doctor will charge you an up front fee. This isn’t just a regular headache it hurts to even look at my phone right now and that’s with taking aspirin extra strength. What do I do. 😞
