How long do you have to file a lawsuit against the hospital for something? Ct scan gave me blisters after I warned them about family allergy.

Did blood test. Nurse said it was ok. She lied. I didn’t see test till after the fact. But I have kidney problems. With as high as it was she shouldn’t of gave me the contrast. I had a severe reaction within 8 hours. I was smart enough to know what to do. They want me to pay this bill. I refuse. Now collections are after me. I have disputed it. If they can’t eat what’s left after what insurance paid. Then I want to sue. I had to go to a regular dr. This was the beginning of a nightmare. No seafood now, have to make sure I don’t eat any ocean food. No iodine at all. Before I could at least eat tuna. I’m scared to even try!!! And all they want is $361.19. Yes I can pay it. But look what they done over a simple test a nurse that could of said no ma’am. Today it’s too high. But she was too worry about either making a quick buck or putting in a needle.
