I'm doing Physical Therapy again, to strengthen the muscles that hold up the bones in my neck (the bones are weak with arthritis, they are compressing, pinching nerves, and radiating pain into my whole shoulder and upper back). It is helping. I did PT for sciatica last year - the pain went away and they taught me how to hold my posture so that it doesn't return. I also do deep knee bends every night to keep quadracepts strong so I can drop down instead of bending over - my sciatica was caused by bending over with legs straight. When my orthopedist used his plastic model of a spine and showed me what was happening to my back and my neck it made logical sense. Peggy
