I have scoliosis, and it was not noticed when I joined the USA military. Then, during a training exercise, I fell down a flight of stairs while carrying >100 lbs of gear.
After medical and a discharge, I was at home and I stood up from my couch only to hear a loud crack and suddenly realized that when people see stars they LITERALLY see stars
My lower back felt like someone had jammed a needle between two vertebrae, and I could see pulsating waves of red and blue over my vision. 0/10, do not recommend. Don't join the military 👍
