Hi .  Our son has very tight archillies and is looking at an operation on both legs.  In the meantime we have found out he has a torn disc in his lower back.  He is 14 years old yet very sporty.  Would this be the cause of his leg problems or would it be a separate issue altogether?
Disc disease is more common in Chat Doctor.  Repeated jerk promote disc ruptures. If he is already having disc problem he should follow back strengthening physio program. I would also recommend that he should avoid games in which chances of sudden bending are more, such as hockey.
