During one of my sets of deadlifting today at 8 AM, I felt a pop in my lower back. It felt like it came from the lowest part of my back slightly to the right of my spine. It wasn't painful, yet I could feel my back tighten up almost immediately afterwards and start to feel weaker. I didn't do anything else involving my lower back after this, and proceeded with my work out.
Throughout today at my job it had been getting tighter and increasingly soar, especially when I took a deep breath and arch my back, or when I slouched forward. I know my form was off on the last deadlift because of fatigue, and that this was the main factor causing the situation. I'm a little afraid that I might have messed something up, so I was just wondering if anyone had any personal experience in a situation like this. I don't think it's bad enough now to warrant a trip to a doc. because 2 Tylenol can do the job.
