Is 60mg of oxycodone and 40mg oxycontin appropriate, for my conditions of pain, chronic and acute

I am in severe pain in the fall, winter, spring seasons, I have fibromyalgia, DDD in my neck, with spurring and arthritis, I also have pain from my Hep C which I have had for 32 years.  I started out on 60mg of oxycodone 2 tabs, 3times a day.  Then, the pain got so bad, I needed 40mg of oxycodone just to get up in the morning, well, I was left with 20mg of oxy, not enough for my pain, I asked the doctor to combine the 20mg oxycontin 1 tab twice a day, then last year I got pneumonia, had a CT scan, because my pain just kept getting worse, he gave me 1more 20mg oxycontin.  Well, I was very happy with this combo, he even let me pick up my perscription early 3 times rather than raising the dosage, during the pnemoina, the coughing didn't do my neck any favors it made the pain worse and I feel it did quite a bit of damage.  He has now decided to take me off of the oxycontin and do this 10mg a day, so now I am on 1 10mg of oxycontin 6 10mg of oxycodone perday.  This caused me more pain and stress, I see him tommorrow and I want 1 20mg per day and 6 oxycodone or 2 - 20mg per day and 3 20mg oxycodone , what do you think of how he did this, in one month each day he took me down 10mg of oxycontin and my pain was twice as bad.  He told me that I was abusing my perscription, and wants me to go off of them.  Please give me your opinion.  I know I don't have a drug problem, I have a pain problem.
