Yep. Sudden muscles contractions can pull something out of whack. Do yoga to realign and relax those muscles.
Whiplash. I have an injured shoulder so happens to me all the time
Yes, it has even happened to professional athletes.
It is possible... I've pulled muscles from sneezes, and occasionally pro athletes will put themselves on the disabled list due to sneeze injuries.
I have been there. I feel for you. :(
Lol! Good luck. :)
It's possible. Or you may have simply pulled some muscles - sneezing requires the sharp contraction of lots of muscles throughout the core, especially in the back and abs.
