My 13 Year Old Son Started Basketball Practicing, And Developed

My 13 year old son started basketball practicing, and developed extreme pain and swelling from the sole of his foot to around his ankle. The swelling was from his arches to under his ankles on both feet. His new basketball shoes were comfortable and seemed to support his feet. Took a week off of practicing, wondering if the pain and swelling will likely to return or resting his feet needs to continue.
