You will be building up the muscles that will support your back helping to stablize the area. This is the same principle as building up abs to support a bad back. The muscles will act as a brace and being stronger may help refered pain. Refered pain is one of life's joys. Listen to your body.

Mine started as electric shocks to my hip which was interpreted by my NP as osteoarthitis, avascualr necrosis of the hip, hip replacement time. Wrong: Hip was normal but L/S spine was not. 2 discs bulging and radiculpathy. Mine was proven by emg and ncv and mri. I rarely have episodes of low back pain. It has increased with the PT. I am giving it time as I have not done anything physical in a year and this may just be my body adjusting to using parts gone dorment . I do have more strength in my legs, balance is so so. If my back hurts, my gait is off and so is my balance and my hip is about the same. I am guilty of trying to do too much to soon and took a big time fall 2 weeks ago at the rehab center. I was airborne, feet off the ground because I was showing off how fast I could walk with my braces. Dumb eh?
