Does anyone else have a problem with their thighs going numb? I have issues with my lower back to where it hurts really bad especially now. Since my appointment this past Thursday I've lost 4 lbs but my belly is steady growing with baby. But even with the pregnancy pillow I end up in this awful pain in my lower back and my legs go numb up in my thighs. Yesterday it was my left and today it's my right. The pain/numbness does not go away on that leg. I do have varicose veins on my left leg. But for the numbness to be on my right too. If anyone else has this issue please let me know, so maybe y'all have an idea on what needs to be done. Thank you!
