When my son had muscle release surgery for his Erb's Palsy, it did wonders as long as the PT continued. He had to have another after a couple of years because as the PT slowed down it tightened back up. He's probably looking at having another soon. My advice would be to never stop the PT. Use it or lose it, or words to that effect lol. Best of luck, hope the spasms/flare-ups stop soon. xxx
