I am wondering why one calf might grow bigger than the other? I was hit by a car when I was 7 and the left leg got cut by the license plate in my upper inside thigh. I thought maybe this could be why? I’ve been to the dr and had an mri and seen a vein dr and they all saw nothing. But since 2012 it has been growing a little more every year without exercise. Any help would be greatly appreciated. I am 26
