cervical cancer/pain medication

I was diagnosed with cervical cancer over 2 months ago. I believed I was going through perimenopause and had a lot of bleeding, however, it got so bad I had to have a blood transfusion, and that is when the cancer was discovered. The first pap test showed pre-cancer, but there is a large tumor 9 cm by 6 cm growing on my cervix putting pressure on organs and nerves. I have only been going through diagnostics this past two and a half months. The cancer was staged just two weeks ago, stage 2 b. It will be three months by the time treatment in the form of radiation and chemotherapy begin. I am in constant deblitating pain. I have an HMO who referred me to an oncologist, and he made recommendations, but my primary doctor is handling my treatment. She gave me vicodin, 3 a day. They did not work, so I called and asked if there was anything else I could do and they said to take 2 tablets 4 times a day. This is not working, it takes almost one hour to start to work and wear off after 2 hours. I called again, and they prescribed norco 7.5 mg and can take 6 a day, but it is the same thing, they wear off early and take time to work. I have been taking tylenol with the norco, about 4 at a time. I called the doctor again and she only said to use just 2 tylenol instead of 4. I am miserable, I am not being treated for my pain, and I am just waiting and waiting for treatment. I do not take more of the medication than prescribed, and it appears that they are worried about addiction. I do not know what to do, and I am being shoved aside like I am nothing. It is very depressing to be in such pain, and waiting so long for treatment. Is this normal to be put off so long for treatment? Is it normal to be denied adequate medication?
