Yesterday I did jumping jacks, post which I'm feeling a bit of sensation running down my right leg. I can only feel it when I walk. Something like a pinched nerve. Not sure though. No pain no tingling no numbness. I have a history of spondylolisthesis and have gotten it checked. The doctor had said since the lumen was larger than expected there was no nerve compression. That happened 3 years ago and there has been no symptoms, which makes me think it maybe unrelated. I've tried stretching but the sensation isn't going away. Please guide.
