Hi Ginger-I love your "gentle hugs"! Very sweet! Thank you!
Iam betting the car trip tightened him up. I drove an SUV for two years after my fusdion and sliding in and out was easy. I traded it in for a more gas efficient sedan and one of the criteria for buying the new car was "could I get in and out with pulling anything?!".It was really a struggle and my back was sore for a few weeks till I got used to it. I have been fused for two years. A four hour car ride is hard! He needs to get out and walk around to losen up as much as possible.I am really stiff after an hour in the car!
I also use the heated seats in the car for my back-it does wonders.
I bet he didn't do anymore damage-just tested how close he is to "normal"
He isn't even six months out of surgery yet-a four hour drive is amazing.
I had to resort to steroid packs twice after my fusion to clear up inflammation. That may be the quickest route to calming his back down.
Keep us posted!
