Suggest Treatment For Pain On Shoulder & Elbows

Hi, I was born with spina-bifida and scoliosis, i am a t-12 spinal cord injury, I lost both legs and left hip around age 17, due to osteo mialitis? setting up in my bones? I think thats what is was called... well anyway, I have used my arms all my life to do the work of both my arms and legs, I am 44 years old and now have a lot of pain in my shoulders and elbows. I recently had x-rays taken of my left shoulder and was told that the padding? between my bones is gone...What are my options at this point? My dr. was unsure of what can be done....any suggestions?
