Lower Back Pain?

Im in mild constant pain in my lower back on the right side of my spine( its getting a tad better with doing my own unprofessional treatment) This Was because of improper Deadlift form and other things, but a couple of days ago i was playing basket ball and I jump for the ball which made me slighty hyperextend my spine at the lower part. When I landed Something Immediatly popped in that area of my right lower back. What Are Some Likly causes of this?
