Hello Doctor, The calf muscle below my knee on the right leg is thicker than the usual on left leg. As thicker calf muscles on my right leg look a little abnormal, I thought it would be good to consult a physician on the same. As I am running 43 years now It would be better to take any kind of corrective actions, right away, if required. I am working for an IT services company. This thicker calf muscle has been there since my childhood. I do not have any kind of specific main symptoms or anything like that, as I do practice leg stretching exercises around thrice a week. Please do advice what needs to be done. Thanks & Regards,
