lol i'm sorry but that just sounds funny
i was crushed between the tarmac and a fat kid.
i couldn't help but laugh at that lol... and the more i repeat it in my head, the funnier it sounds.... not laughing at your pain or nothing, i can guess that would hurt pretty bad, hell just a skinny person smashing you into the pavement full force would hurt...

i'm guessing my back probably isn't as bad off as yours... maybe it's because i tollerate pain very well (it's practicly the only feeling i've known my whole life) or something... but i'm not in constant pain... i mean the slightest thing can send me into days agony... i remember one time after sex my back was hurting so bad it kept my breath away from me (didn't actually 'knock' the breath out of me as there was no real knock to do so, but same feeling nonetheless) didn't stop hurting again for the next 2-3 days... if i'm not careful, i can put myself in pain for the next few days just lifting something as heavy as a 24 pack of soda's or a big bag of potatoes..
