Do you sit for a long period of time? I get that feeling sometimes from sitting too long on the pot with my elbows on my legs while leaning forward and possibly just pinching a nerve a little bit. The tingling feels like my feet and/or calves fall asleep. Never lasted more than just a few minutes though. Alway figured that was just from sitting too long on my throne(King of the toilet-lol). Usually try to move my body a little bit every now and then while I'm sitting there and for me, I usually avoid that problem. Other than that, I have no idea why that would happen to you. Good luck.
