Hi, my name is Tasha, I have been having terrible trouble out of my left leg for years. A couple of years back i had a bad fall on it and it has been giving me trouble ever since then. I have been to the doctor and my leg is still giving me trouble. My left knee cap is on the right side of my leg and is hurting when i try to bend it straighten it or even sit with it out. I have been to an MRI and still haven't gotten my results. So i'm here to try and find out what could be done about it. Or if i need surgery, the doctor i went to thought it was my cartilage.. but I'm not sure whats going on. IT pops and cracks and grinds against my bones it feels like, is there anything you can do to help me out with this problem?
