I had laminectomy and discectomy on L4/5 4+years ago. I went to Disneyland last weekend (rode the roller coaster)and carried luggage down a flight of stairs - and then sat in a car for a 8 hour drive. I have been in presurgical pain for the last 4 days. I have done this before but it always got better. I am a bit scared this time. Any suggestions or calming advise!
