I have MS and have trouble rotating my left leg out. Which exercises could help me?

The "Unlock Hip Flexors" program can definitely help your condition. This program targets the tight hip flexors. Because some of the hip flexors muscles are also internal rotators of the hip, it prevents you from rotating the hip externally. Because of this tightness, your gait is extremely affected. I recommend that you check this link to know more about the program. Should you find this helpful you can proceed with your order using this link: http://healing-through-movement.com/order-10/.
