For all Tiger return/congressional talk, go HERE
We're going to start moving away from these "mega threads" so it's easier for people to find more specific topics.
In my experience, pain in the low back like this doesn't clear up easily. I think he was probably sore and more pride hurt than anything since he is at Val Halla now.
Personally I think the majors are more important to him than the Ryder Cup. I may be wrong though.
I doubt your experience is similar to every kind of lower back pain anyone can experience.
I have always suffered from back spasms since an injury to my lower spine at an early age. Funny thing about spasms forming in the lower back is that you can be strong with a full range of motion and then all of a sudden it catches and your back goes completely out. You can't walk at all, can't even stand all the way up. All I could do was lean to the side of least resistance. It can also go away suddenly but you STILL don't quite trust it. I was walking to get my mom's mail one weekend about 12 years ago and got hit with a lower back spasm and fell backwards while walking and layed in the grass for a full 30 minutes before my mom looked out the window and saw me laying out there. and as Tiger said you CANNOT TWIST past maybe 40%-50%. At least for me anyway.
