If your child's foot or ankle is hurting it may be due to a condition such as ingrown toenails, sports injuries, Sever's disease, plantar warts, or pediatric flatfoot. Untreated foot problems in childhood can lead to chronic problems later in life. Arthritis can set in where a bone was fractured and a bad sprain could lead to weak ankles and recurrent injuries. It is better to err on the side of caution and have your child see Dr Ripepi for early treatment.
