Is your leg numb/burning/stabbing? Sounds like sciatic nerve and you have to do stretches to get rid of it. I just found out that's why my leg/back feels that way and its been going on this whole pregnancy. My doctor said prenatal massage, stretches (the 'scared cat' where you're on all 4 and push your back up like a scared cat then relax), or if that don't work they are gonna put me in physical therapy. Hope this helps!
If you havent invested in a prenatal massage you should definitely get one!
