My son bit through his tongue when he was 2, luckily he didn't need stitches but it bled so much. The smell from all the blood was horrible. And eating was tough for a few days.I bit through my tongue ( I was about 10) bizarrely that actually wasn't painful. The painful part was having it stitched back together. They had to inject my tongue up the sides to numb it. Omg I can still remember it.Just awful. Got home and the stitches burst so had to have it done again! I've had 4 children and swear that wasn't as bad! After pains were horrendous with my 4th though.
My worst pain was a ruptured disc that pushed on my nerve. It got so bad that I lost bladder control (couldn't go pee anymore). Went to the ER and and they kept me and did surgery the next day. The pain was so bad that at one point I thought maybe if I would take all the pills in the house I could go to sleep and never wake up. I have never had suicidal thoughts before that or after.
