So about 2 months ago I deadlifted more than I have had in the past, using the hex bar. I felt pain in my lower back but didn't think about it much. The following days the pain was very sharp and painful, hurting to pick up objects, bend over, stand from laying, and especially deadlift.
I stopped deadlifting since then, and the pain got better over time. Although the pain diminished, I still felt it when stretching to touch my toes, and holding an L-sit position.
I could high bar deep squat without pain however, and I pushed it to the limit squatting a one rep max a few days ago. I got the max with clean form, no problem. I tried the same weight again a few minutes later, and I leaned forward and used way to much lower back on the way up. I noticed sharp lower back pain during the squat.
So basically for the last 5 days my lower back has been killing me. It hurts just as bad as it did 8 weeks ago, but now it hurts to bend forward and to lean back. It stings in addition to the sharp pain after using it. And the pain seems to be more on the left side of my lower back. Kicking my legs up while standing hurts too. It hurts to stand from a seated position on the floor without using my hands.
Any idea what this is or who I can see about it if it doesn't get better? There is no shooting pain down my leg so I don't think it's a herniated disc. Could it be a pinched nerve? A strain?
