I hope someone can help me with this...I have a weird feeling that is radiating from my tailbone (for lack of a better description: starting at the top of the crack and going across the top of my buttocks). I can best describe it as kind of numby/tingly sensation that makes me feel weak throughout my buttocks and legs (hamstrings and calves, not quads) that has been with me for 7-10 days. I cannot remember any impact on my tailbone, but was working out a lot during the week leading up to this including intense leg lift workouts where my hands are under my lower back and I think that may have caused a nerve to be pinched or something. There really isn't any pain. I feel like the sensation gets worse, or more intense but still no more than a 3 on a 1-10 scale, when sitting and leaning forward (e.g. elbows on knees). Has anyone heard about this before? I couldn't find anything on the web, mainly because I am not experiencing pain only this weird sensation. If you know what this is, please give me some guidance this is driving me nuts!
