I am uninsured and need something similar to a primary care visit. i think i need a colonoscopy. any advice?

Obamacare: Given the medical history you have listed, and the fact that you are on several chronic medications, it sounds like you need health insurance! a colonoscopy alone can cost a thousand dollars! your options depend on your state of residence. Check www.Healthcare.Gov for more info. Check with your local hospital to see if they have a low cost primary care clinic or charity care program.
