Ankylosing spondylitis is a type of joint inflammation that influences the spine. Ankylosing spondylitis side effects incorporate agony and solidness starting from the neck to the lower back. The spine's bones (vertebrae) may develop or intertwine, bringing about an unbending spine. Ankylosing spondylitis influences something like 0.1% to 0.5% of the grown-up populace.
