latissimus tear??! need your help

[spirit]

Hello everyone,i have been always doing deadlifts and from time to time i get strange crumbling noise in rear delt and then big pain,so i cannot continue my workout and i stop.This haven't happened since 6 months when i started doing deads again .Today I deadlifted 500 pounds for 1 (not a big problem) and i haven't changed my style or something and just when i managed to get up i felt strange noise like crumbling into rear delt/lat and then pain.Last time this happened was 6 months ago and on the other day i had a small bruise with a bit of hematoma but it was gone in 5 days and next week i could do almost the same weight.I was pissed this time so much i had to stop my workout because i couldn't pull nothing more than a 45lb plate and got home.Do i need more stretching or more assistance excercises because that shit is pissing me off,please help

You need to warm up more before working sets and yes that means stretching as well
