Hi. I am sorry to hear about your situation. My husband and I have no health insurance either. I was in the process of choosing health care when I became ill and was diagnosed with lung cancer. My husband has Wilsons disease and no one will cover him. We were able to pay some of the bills as we went along with the testing to find out how to treat my cancer, but the hospital bill was another story. We talked to the financial person at the hospital and was able to pay 60% of the total bill. They actually knocked 40% off. We had to come up with rest however rather quickly. Some hospitals will take payments and will set up a payment plan. Talk to whoever is going to treat you. Doctors and hospitals, radiation or chemo docs too. See if you can pay them a little at a time. Also disability, Social security or maybe your county hospital. Those would have been my next choices. Good luck to you and let us know the diagnosis when you find out. Don't dispair when you are not yet sure whats going on. I know clubbing can be caused by lung infection also, not just cancer.
