Over time, I started having sever pains that shot through my abdomen and groin. I could barely walk. I had tried to go to the SF General hospital, but it took about a month to be seen by a general practitioner. I finally did get seen and they thought it could be a hernia, but were unsure. They scheduled more tests, which was about a 6 month wait. (I should note that SF General gets a lot of unusual people and the staff gets slowed down from dealing with the more difficult patients.)
Desperate, I found a small hospital clinic and asked them to see me. I told them I had to pay out of pocket. Oddly, the doctor who saw me gave me a huge discount. He diagnosed that I had sciatica from bad ergonomics. Sure enough, changing how I sat improved my pain! I was lucky. Very lucky.
Now, my sister is currently struggling with a serious issue, and as a Medicare patient (being under the poverty level), she wasn't able to be seen for months, and even now they are unable to diagnose properly due to delays in getting her referrals or tests (CT scans, etc).
I can't stress enough how uneven and cruel the US healthcare system is. I feel the only way to survive long-term is to have a career that enables access to jobs (or unions) that offer health care as a benefit. Without it, paying for family-level premiums is similar to a mortgage.
