This AM, I woke up with my left ankle in excruciating pain, I couldn't walk on it. I did not twist my ankle or anything. I'm getting around with a cane. When I sit, the pain radiates up to my left butt cheek. Almost like it's traveling up and down the nerve. I tried using liniment on my ankle and it gets warm, but doesn't affect the pain. I'm sitting on a heating pad and that helps the rear end pain, but not the ankle. It's not gout, because that is in the toes and doesn't radiate up the leg. Any suggestions? No trolls, btw.
