Ankylosing Spondylitis

30M from India. Been suffering from Ankylosing Spondylitis for the last 3 years. Taking Sulfasalazine 1000 twice for 6 months. Barely making any difference. Haven't had a day without inflammation. The only thing that helps reduce pain is hot showers. Do I have to live with this for the rest of my life or is there anything that can be done?
