Weakness in the leg muscles, contracture with limitations in the movement in the joints of the legs or feet should be evaluated by your physician immediately.
When a child complains of soreness in the legs it is frequently said that they are having "growing pains". In fact the act of growing is not a painful condition. "Growing pains" indicate that something abnormal is occurring. The muscles in the lower leg control the function of the foot. When the feet are not functioning properly it causes the muscles in the legs to fatigue. This fatigue results in soreness or cramping in the muscles of the legs. This may manifest itself early in development of the child. A newly walking child may prefer to be carried or held instead of exploring their new world. Youngsters may protest walking in the mall or at amusement parks, tiring easily during a fun adventure.
Treatment consists of using custom molded inserts for the shoes called orthotics to correct the underlying abnormal foot function. This in turn reduces the stress experienced in the leg muscles and will ease or eliminate the soreness. The results can be quite dramatic with a rapid improvement in the child's symptoms. As with all medical treatments results may vary and orthotics may failure to resolve the problem.
