I am nearly 16 weeks with twins. I have only gained a couple lbs and am not really showing. That being said i already have extremely severe sciatic pain. Shooting down my leg and occasionally numb toes, but constantly excrutiating in my butt cheek. I had spine surgery in 2013 where i had 80% of my disc removed from the l5 s1 level. I was cleared for pregnancy even though i have a conjoined nerve root at that level. (Two nerves coming out instead of one) i have been doing planks, some light stretching lunges aNd squats to try and strengthen. I have also done some suggested stretching. What else can i do? When my back hurt bad before it was from swelling and i would take advil for a couple days and i would be fine. Now i feel like i have no options.
