finding help

I have chronic pain all the time in my arms, hands just the the whole body. I have diabetes under control.  But what so bad is I can not function any more.  I am alright if I sit still, but if I walk even A short distance I get very sick the rest the of day.  I just wanted to know what is wrong with me.  I have had x-rays and I do have arthritis in my neck, back, knee and hands.  I am under a doctor care.  I seem to be getting worst no matter what medicines I take.  Oh by the way I am 61 years old.  I just don't like the nausea when I doing anything like clean my house, work or just walking from one place to other, like across the room.
