I have recurring back pain/injury that gets aggravated from deadlifting. It happened again today. I was in the negative part of the rep when I felt the lower right part of my back give out or weaken. I was still able to execute the rest of the set(probably a mistake) but for the rest of the day I have been experiencing pain in that lower right part of my back. For example, if I were to bend down to touch my toes, it would hurt pretty bad. That area of my back just seems vulnerable to this type of flare up. Sometimes I can go through 3 or 4 months of pain free deadlifting but i always seem to reaggravate this injury and it really takes all the fun out of deadlifting when it happens. I am aware of the value of the deadlift and would hate to have to stop doing them. However, I am concerned with this back pain.Any thoughts or suggestions would be appreciated.
