I've had this condition for about 10 years, and I've always assumed that it has to do with compression of a disk in my lower back. I believe it began when my second child reached 1 or 2 years old. I used to carry both of my daughters up and down the stairs -- one in each arm -- from birth until my older girl was around 7 and my younger girl was around 5. Recently I planted a number of heavy trees, and also spent time in a pool tossing my younger girl (now 10) repeatedly. Is this treatable without surgery?
