Have you ever had an injury or done extrenious workouts? Have you ever moved a couch for someone? Have you ever had rough sex that leaves marks on your body (or hers?) Have you ever been bitten by a dog or scratched by a cat? Have you ever been sick or had a fever? Have you ever been drunk?

Use those real world experiences and insert them into the description without actually saying they feel like those. Instead, describe them how you would a real world event.

Don't say something like... "My back feels like I lifted a couch!"

Instead, write something like. "I couldn't move and when I tried to there was an incredible surge of pain running down my spine! It was hard not to panic and panicking only made it worse."

Stuff like that.

Good luck!
