How much is the average ER cost in California?

whoa. that's even more than the value of my paycheck :(

holey moley! i think i got it from naproxen. coz my right knee was hurting so i took naproxen and on the next day i woke up with rashes all over my body

Ever taken it before and nothing happened? If this is the first time you've ever taken it then you'd probably put it off to the side and stick a warning on it until you can figure out whether or not it gave you this rash. As for going to the emergency room, it would depend on the severity of the rash and whether or not you think it's getting worse. If it's a few patches of itchy red spots and they seem to be fading then I'd just wait awhile to see if it clears up on its own. If the spots are so bright and vivid that you look like you've got the chicken pox and it's only getting worse, then you probably need to see a doctor. I'd see if there's a health clinic or doctor that will see you instead of trying to go to the emergency room because those visits are hugely expensive.

just came back from doctor's clinic. they charged me 160 dollars for the consult and 10.99 for the medicines and that's a whole lot better than a thousand dollars! thanks for your advice! :)
