We were so excited when our best friend finally became pregnant. She and her husband had been trying for years and it seemed as though their dreams were never going to be realized. Then she discovered that she was expecting. An avid reader, I think that she had already read every possible book on being pregnant. One thing she definitely wanted to avoid was a sciatica pregnancy. When the sciatic nerve is pinched by the growing baby, severe pain can affect the lower back and upper thighs. Walking, even moving can become agonizing. My best friend started walking everywhere she went. She became a health nut to make sure her baby was getting as many nutrients as she could give him. The baby arrived safely and right on time. Now my friend is reading about the rest of his life.
