Hi. Our 3 year old son had kawasaki disease in sept 2012. He complains a lot with pain at back of knees and his back. Could he have arthritis?
It's possible. . According to the arthritis foundation, kawasaki disease is one of over 100 types of arthritis. Arthritis or arthralgia can occur in the first week of the illness and tends to involve multiple joints, including the small joints as well as large weight-bearing joints. Sometimes back pain in children could be related to low vitamin d levels. Vitamin d blood levels should ideally be 30-50 ng/ml.
