I can’t remember if my leg felt this funny last time or if my adventure into giving myself the PIO shots has gone awry. Whenever I touch the PIO knot in my left buttock, the left side of my leg tingles, about halfway down my hamstring. Weird.
That happened a few times to me as well. I think you probably just hit a nerve during the shot. it should go away. If not, contact your doc just to make sure.
