Going to the doctor is not fun. I just do it because it;s necessary
Agreed on both counts. What's even less fun is having to go to the doctor and having him run a slew of tests you can't afford. Worse is being diagnosed with something that will be expensive to treat and not being able to afford that. The PPACA makes it possible for more people afford to (A) see a doctor and be screened for common conditions and (B) pay for any treatment they need.
I personally experienced my premiums going up and many hospitals and doctors refusing my health care plan.
If your premiums have gone up, you need to contact your insurer and find out why. if they can't or won't answer you, you need to find another insurer.
As for "many hospitals and doctors" refusing your health care plan, that's also a function of the insurer. Have you asked them why? When you say "many," how many are you talking about?
