Dear Sirs, Four years ago I had problems with my left hip, it was jumping out of cup when I was walking and had pain afterwards or in that moment. I had to watch how I walked. Then problems disappeared, but last week after running I started to have same problems and pain. I have X-ray and MR footage from six months ago because of my lower back pain problems, where you can see hips to. I am male, 27 years old. Hope you can help me.
