While I bent down to pick up my map, I felt a sharp pain near my right kidney
. While I stood back up, the pain was so severe, I couldn't hide it, and
I was having trouble breathing. My pain was obvious, and it caused a co-worker to call for help. It literally felt like somebody punched me there so hard, it knocked the wind out of me. This lasted a good 30 seconds before the pain finally subsided. Later, when I came home from work, it almost happened again while I bent down to pick up my cat.
