I Have Chronic Pain My Joints Swell I Flare Up

I have chronic pain
My joints swell
I flare up and can barely walk
I am on cpp disability
I am 55
It seems to me that I am being told it's all psychological
Please help me find some answers.
I am living like I am dying.
Nothing seems to help. It's all hit and miss
I have been to pain clinic and that was scary I ended up paralyzed until the drug wore off
I live in Barrie Ont.
My shoulder and hip is the worse.
The pain is so bad I can't see clearly.
I know I'm young but feel so old and some days just want this life to end
I am a Christian. I am in God's hands
I just need to know what I can do to find out what's wrong with me. Please.
