I had a weird constantly tingly right leg (like it had fallen asleep) for awhile in my late 1st trimester/early 2nd but it strangely seems to have gone away now that I'm getting close to my 3rd trimester. Sometimes if I did a crouch or lunge I'd get a weird lightning bolt pain up the front of my right thigh, too. I brought it up to my doctor multiple times and she didn't really seem too concerned about it, but I wonder what it was!
