[Health Question] Ankylosing Spondylitis

When I was a high school senior, I suddenly experienced severe back pain and went to the emergency room. The diagnosis was ankylosing spondylitis... It was shocking news, and especially as my body gradually became more rigid, I was told it was an incurable disease. I still live with pain every day, and my back and neck are quite hunched, making daily life uncomfortable. I try to walk at least 10,000 steps a day and do as much exercise as possible, but do you have any good information about ankylosing spondylitis? If anyone knows about diet, exercise therapy, lifestyle habits, etc., please share.
