A Week Ago, I Bent Forward, And Before I Picked

A week ago, I bent forward, and before I picked anything up I experienced severe pain in my lower back. I had trouble walking and moving because I would get shooting pains up my back. I used ice, ibuprofen, and I got an adjustment. After a few days I was able to walk but bending my back forward and backward and getting up and down still really hurt. Now my lower spine is very tender to the touch and bruised. My upper pelvis also hurts on the right side. It also still hurts to bend forward and back.
