Severe Scoliosis Pain But Not Severe Enough for Surgery?

I’m 19 yrs old and I have moderate to severe scoliosis. 37 degree thoracic dextroscoliosis / throracolumbar levoscoliosis as well. I’ve had chronic pain for 5 years. I’ve tried a multitude of treatment options including bracing, chiropractic, massage therapy, yoga, tizanidine, etc. My doctor claims my curve isn’t severe enough for surgery. However, the pain caused by my scoliosis is constant and my X-rays are always confusing. My doctor only listens to my X-rays instead of listening to my concerns for my increase in symptoms and worsening pain. I have to schedule my yearly appointment with that same doctor. But everytime I go he always says there’s nothing he can do. What should I do at this point? Has anyone else had severe pain but not severe enough of a curve to qualify for surgery?
