Lisa Ann- I lost my Dad to this illness in January of this year. He was 69 and in pretty good health. His illness was diagnosed at Stage 4 and was quite aggressive- only having been diagnosed when he experienced pain in his hip. No one could believe he was as sick as he was when diagnosed- he didn't look sick nor did he really complain much. They discovered he had extensive bone metastasis and 4 weeks later found the primary to be CC. He too had lost about 25 pounds and was constantly vomitting, having no appetite and difficulty sleeping.
His doctor prescribed pain meds immediately. He began on Tylenol 3, then went directly to Dilaudid upon diagnosis. I too was frustrated at the length of time between appointments.
Looking back, one thing I'd do differently was actually take my Dad to the Emergency ward. At the beginning we waited for his appointments. For him, it would not have changed the outcome because his illness was very advanced when discovered. However, had I taken him to Emergency before waiting for the appointment, he would have had the proper treatment for his pain sooner. They have oncologists on call at hospitals and they will prescribe a pain medication for him.
This is something you can take control of now... he doesn't have to suffer needlessly. If you get resistance, ask to speak with an advocate. In this day and age, there is no reason that an individual needs to be in pain.
We lost my Dad within 10 weeks of diagnosis and it was the most difficult time in my life. My comfort lies in the fact that my mother and I were his constant support and we were there for him until the very end. Regardless of what happens, your dad needs to feel your support and love.
I wish you peace and strength. My prayers go out to you and your family that your dear dad is well taken care of.
