Hi, I am a 47 yr old male suffering from hip, lower back and leg pain which causes tingling and numbness in my legs making it unbearable to walk. Relief comes if I sit down for a while. I currently weigh 60kg, am of very slim build with little body fat and don t appear to have much between my bones and skin. I have started to urinate more frequently than usual. Whilst I have been to several doctors for tests etc, they have only prescribed vitamins C & D, which has not helped. I would appreciate a diagnosis of what s wrong please. Regards Ashley
