"Lack of understanding by doctors"

I have chronic pain and I feel very tired of being let down by my doctors. Several times I have tried to get an appointment with the doctors and they have called and given me an appointment in person which they expected me to attend with in 15 minutes. I live on the other side town and I’m in a wheelchair so my husband has to help me dress, get to the car park, get out of car, get to the doctors. Then if I’m late by 5 minutes they won’t see me. So I can’t go to the doctors when I need them, I spend days in bed in pain with infections and with no help. I go to the hospital they don’t know how to treat me. My doctors have not even been able to put a pain plan in place. I feel like they don’t care.
