My 12yrs old daughter has frequent pains in both her knees (more) and ankles (less). it feels sore, tightening followed by a burning sensation that makes it painful to continue walking or standing. mostly happens when shes been sitting and gets up.

Knee,ankle pains: If these symptoms resolve quickly after getting up from sitting and walking around, this is most likely not an inflammatory process like juvenile rheumatoid arthritis, but could be a variant of growing pains seen in that age group. Nevertheless, for validation I recommend consulting a rheumatologist for proper evaluation and advice. Any appropriate tests will be ordered.
