腰を痛めて三歩も歩めず。
＊＊＊＊＊＊＊＊＊＊＊＊
それは突然やってくる、恐ろしいギックリ腰。
（私はそれで二週間寝たきりになったことがあります。トホホな思い出・・・）
I got strained back, so I couldn't walk even just three steps.
*************************************************************
It is truely out of the blue. That's terrible!!
(I've got that experience many years ago. I was on the bed around for 2 weeks, like cabbage...it's one of my bitter memories...)
*not sure about my English...
