Ankylosing spondylitis (AS) belongs to rheumatology, and originally belongs to rheumatic immune disease. It doesn't cost much to detect the disease, but it may take you a lifetime to see a doctor. At present, the cause of the disease is unknown, and the drug is only imported, which costs about 654.38+ million. If you have this disease, if you have no money, take painkillers+inexhaustible Chinese medicine+gymnastics control every day! If the disease can only be controlled, it will be good for life. If it is not well controlled, people will die. I didn't scare you by saying that. If you suspect that you are ill, go to the hospital for examination. First, take a film of sacroiliac joint, and then draw blood for tests: ESR, B27, C, C reactive protein. If your sacroiliac joint is inflamed, there are gaps, ESR and C-reactive protein are too high, and B27 is positive, then I can tell you that 100% has ankylosing spondylitis!
