Many times after a hip replacement one leg will be longer than the other leg.  Over time what can happen is the side with the short leg will take too much stress, and the hip or knee can wear out. Many times the spine will also become crooked.  I’ve done 3 sessions on a woman with these problems. She has excruciating pain in the knee, and lower back. The hips are crooked which hurts the back.  I am able to straighten bones very easily, but I didn’t know about this artificial hip which is misplaced, which makes the leg longer. So I tried an experiment and ran energy into the hip replacement, hoping that the structure supporting the  hardware would realign. On the 3rd session it did!! Now legs are even, hips are straight, spine is straight all the way up to her neck. She has no pain, and is practicing on walking upright, and straight. Remember the muscles are used to being abnormally stretched, or short. She is so excited because she can walk now, and goes outside every day to do so. Next session I will have before and after pictures for you. Light and love!
