I hear you. After getting tired of being couped up this weekend, I mowed the yard and did other misc. things, even took a drive in the Lotus, which is like getting in and out of a go cart, and my back felt better than ever. Left side is still sore, especially when sitting in an office chair, but hopefully that too will pass!
Stay active! As soon as you can get around, get walking and don`t stop moving. I have chronic pain in my lower and mid back. Driving makes it hurt the most. The only time my back does not hurt is when I am hiking and riding.
