Dr. Lin Yunfei
Ankylosing spondylitis (AS), a chronic inflammatory disease affecting the spine and joints, typically presents with symptoms concentrated in the lower back and groin area—namely pain and stiffness. When patients experience foot swelling and pain, these symptoms are generally not direct manifestations of AS. Rather, foot swelling and pain are more likely attributable to other conditions, such as gout or arthritis. To achieve an accurate diagnosis and appropriate treatment, patients require further medical evaluation to identify the specific underlying condition. Although foot symptoms are not typical in AS, lower back and groin pain are common among affected individuals. When such symptoms arise, patients are advised to promptly consult a physician for professional assessment and treatment recommendations.
