Welcome to the forum. I have a lot of leg pain as well and it is a nerve/lumbar spine issue like Vicki said. I also would talk to your doctor about an MRI. Contact a pain management center if possible and also keep a journal of your symptoms, activity, when you take medications, your sleep patterns, etc. When you take that with you to your doctor it gives them better information and then they can know better how to treat you. Good luck.
