Members overwhelmingly confirmed that joint popping after a flare-up is a common experience with AS, with many describing loud cracking and popping in their knees, ankles, hips, back, wrists, and fingers that often happens daily but worsens after flares or during cold, damp weather. Several members shared that the popping sensation often signals inflammation subsiding or joints shifting, though some described an uncomfortable wiggling or moving feeling in the lower back that can be attributed to muscle spasms. A recurring theme was the importance of staying active through daily stretching, hot showers, physical therapy, and using tools like portable TENS units to prevent joint stiffness and fusion.
