Throughout my pregnancy the baby has been sitting directly on my sciatic nerve. This nerve has been sending shooting pain down my right leg and up my back. Most of the time Brett can find this point and push really hard to relieve some of the pain. Brett's mom found these amazing "Blue Balls" as we call them at Costco. They are the BEST thing for my back! Lynn was so great and came home with a set for me one day! I use them almost nightly to relieve my back pain. Anyone else who is pregnant with a throbbing back, do yourself a favor and go get some Miracle Balls!
