When you have a hip removed, one leg will be shorter than the other. No matter how hard they try you can’t get a shoe built up that will provide the perfect support. My hip is curving, plus I now have artheritis in the back. This is causing back pain, plus my sciatica is aggravated which causing pain. This is one reason I tell people to always use a walker or at least a cane to help you stand as straight as possible.
