I had decided to clean our fish pond. The first step was to fill two large tubs with pond water and transfer the fish and pond plants into them.
As I lifted the second tub out of the pond after filling it up, I felt a pain in my lower back, but I was able to continue. When I was almost finished emptying the pond, though, I twisted to fling a bucket of water, and this time the pain was much more intense.
I collapsed to the ground; I couldn’t move or stand up. I lay on the ground for some time before crawling back to the house.
