It would make more sense if you read the posts and responses in chronological order.
He only mentioned his back after I had mentioned ligaments and tendons.
Do you think the spine doesn't have tendons and ligaments attached to it?
I think you are just spoiling for a fight?
You are correct he did mention the back AFTER the fact in post #5...but then you continued on with the lifting heavy equals injury AFTER that.
Did he mention it was a tendon or ligament injury in the back or could it be something else?
I'm not spoiling for a fight, simply pointing out the inconsistencies in the assumptions you're making.
