From time to time, I have Left buttocks, hip and left leg pain. Slightly, in my groin area, too. Been going on for a few years. It's not chronic but happens, at least, once every other month and lasts several days. I do a lot of walking at work (Mail man) and last week I stepped off a curb and fell. Pretty hard fall and the pain I was talking about has been aggravated ever since. Any ideas? Someone mentioned Sciatic nerve pain, but I thought that was chronic. I would like to start back on my treadmill again, but not sure if its safe.
