My husband had a Laminectomy and a Tethered Cord release 3 weeks ago. The doctor told him to not bend, lift, or twist for 2 weeks. Also to not drive. He was told to start taking short walks around the house and then increase them. We have been doing what was told but his pain is getting worse. He has intense back, leg, abdomen pain on and off. I tell him perhaps it is the nerves coming back together. What can we do to prevent this Chiari that I am reading about? Nobody mentioned physical therapy. Would that help? Does UltraSound prevent scar tissue from building up? Would wet heat help like from a spa? Is there a lose time table on how long a recovery is?
