Emergency Room

I don't understand how the whole emergency works even though I work in a hospital myself. Every time I go to the ER , they never can find out whats wrong with me and tell me to go to my regular care provider. People sit in the ER for hours just to be sent back out the door with no diagnoses. I feel like doctors in the ER should try their best or keep people over night to figure out what's the problem. The other issue is most doctors in the ER think people just come for pain med to use as drugs. There is actually a law that says something of the sort that if someone says their in pain , then you have to believe it. I've been having my certain problem for over 5 months and no one can tell me what's the matter which really sucks. It's like hospitals around here are a big joke ! If I could , I would go to Duke hospital or somewhere further to get better care. Guess I just need to find a primary care giver again , I'm just over the health system and how it works at this point when it comes to solving health problems for certain people. I take pain pretty well but I feel as if I have to go into the ER acting all crazy just to get some help , I shouldn't have to do all that. . . . . .
