I get a tingling sensation down my leg to my toes every time LO is sucking. It tingles on whichever side LO is nursing from, like the feeling you get when your foot falls asleep but it keeps happening over and over. I've tried different positions but it still happens. It's only when he sucks and the seconds he stops to take a break, it's gone. Anyone know why this would happen? It's not painful but concerns me, as it has been going on for 2 months now.
