Her: Yes, yes! And your mother's ring! It's beautiful!
Him: Her ring? No, no... the ring was my mom. She's the diamond, just look how she sparkles!
Her: Ewwwww! (Runs away.)
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
