The full answer
Yes — joint pain is a common non-digestive symptom
Joint pain and inflammation are reported by many people with celiac disease, likely related to the broader immune activation involved in the condition rather than the joints themselves being directly attacked.
It can overlap with other autoimmune conditions
Because celiac disease is more common alongside other autoimmune conditions, unexplained joint pain combined with digestive symptoms is worth discussing with a doctor as a possible sign of celiac disease specifically, not just general inflammation.
Important context
Individual symptoms, reactions, medical histories, food products, and local labeling rules can vary. Community experiences are not medical evidence.
For personal medical decisions, diagnosis, testing, or treatment, consult a qualified healthcare professional.
