You can go, sure. They won’t arrest you. Nevertheless, if you don’t have something ER-serious, they won’t be of much help.
You’ll get a polite suggestion about seeing a specialist.
Thank you for your good wishes, and same to you as well.
As for an ER doctor giving you a polite suggestion about seeing a specialist, perhaps, after they’ve eliminated any life threatening possibilities.
Then the uninsured, as I was for decades, can find a GP in the phone book, ask what a visit would cost, and either bring the money or a credit card to pay for the $75-150 visit.
My current GP charges $125 per visit and it is an excellent fully staffed clinic with hep doctors and a professional atmosphere, good response time, etc. I know the fee because I asked first. I have a high deductible policy and pay for all my visits, labs and prescriptions by check or credit card.
