Hello, I Was Told When I Was 11 Years Old

Hello, I was told when I was 11 years old that I have scoliosis and rheumatoid arthritis, and I have spent a lot of that time in and out of pain, some days I couldn't get out of bed without help but I pushed myself and played sports during the times that it eased up but now its bk as monstrous as ever. There are days when I can barely walk, my spine feeling as though it is separating, burning pain and sweeping in what feels like all the bones of my hands n wrists, my neck n shoulders but how can I know for sure this is what it is? I was really young and I did go to an orthopedist for years then chiropractor for another decade, I remember the painful exercises I had to master that eventually helped but I don't remember all the tests they did because ii had other health problems and was in and out of surgery twice a year during this time also. How can I be sure?
