Input: Text: so this happened yesterday, not today.
i was rather stoned so i was kind out of it. i was on my way downstairs, the stairs have carpet overtop, that kind of worn down and old carpet that is slippery when you are wearing socks; of course i just so happened to be wearing socks and i was also moving at a rather fast pace, so as you can imagine i slipped. here's the fuck up, i landed right on the 4th stair, on my lower left back with all 220 pounds (i'm almost 6"1' tall) of my body going straight onto my back. i then slid down the stairs, still processing what just happened. i didn't realize until i stood up that i had caused my **already sensitive** back some of the most ungodly back pain ever. it honesty hurts to the point that im considering seeing a doctor.

 
i slipped and fell down the stairs, landing with my back right on a stair. my back is very sore now and literally anything hurts.

edit: gonna see a doctor soon, will update the results

edit: the doctor said there's been some bruising and pulled muscles, but there shouldn't be any sort of major permanent damage. fingers crossed it will get better on it's own!
