I am kite surf instructor but have spine condition pain too much too handle?

I am a 26 years old female kite surf instructors. Few years back I had few test done on me including an xray. They told me I had some kind of spine condition, told me not to kitesurf and that I’d be fine. Now I didn’t completely stop I still teach and do other sports like paragliding, snowboarding, speedflying ect. But some times the pain in my lower back is too much to handle. What do you think I should do about it. I don’t want to take pain killers I would prefer to actually fix my back so I can do everything I love doing. Please help me get back on my feet.
