I'm actually in the health insurance biz myself and had this same problem two years ago at 22 years old, which is somewhat uncommon for males but not females. Get some insurance fast and ask about prexisting condition clauses. This turned out to be a gall bladder problem for me. Liver enzymes can tell a lot of things about your upper GI. Talk to your doctor after you get insurance, he/she may request some radiology on your gall bladder. I recommend it, although it took 2 ultrasounds and a 2 radiology tests to determine that I had sludge in my gall bladder and that it eventually died.
In the mean time, dont eat foods with a lot of fat or oil. No McDonalds, Ranch dressing, heavy cheese or Taco Bell, which my doctor said to stay away for life

A new aquantaince and I had ours removed at the same time after we both became addicted to Olive Garden's artichoke spinich dip. We finally met 3 weeks ago and we had the same situation. Stay away from anything thick, fried, fattening or oily.
These gall bladder removal surgeries are common, so dont be afraid. But they do take a long time to get into. Mine took a month, some up to 3 months. In the mean time, your doctor may perscibe Nexium ($50 per miracle pill) if your insurance covers it or Percucet. They work wonders.
Your main goal is to get insurance that will not classify this as a preexisting condition. Avoid one with high deductables, because you will have to pay them before your bill is covered. Ask about the perscription tiers and the provider/facility tiers. Then see your doctor.
