'Bruised' Feeling in Lower Back

The fun never ends.

So, for about 2 weeks now, i have this weird pain in my lower back, right at the “bump”. Just normally walking around and such, doesnt hurt.

When i cough i can kind of feel it, but if i roll it or dig around it with my fingers, it feels “bruised”?

Ive laid off of really heavy deadlifts and squats for about 6 weeks now to really let my other issues get fixed, and focusing on benching.

Just curious what this could be? i do use an arch while benching, could this be why? I have no numbness down my legs or any “sciatic” issues. But reading around it sounds like disc injuries are like chaos theory. no one really knows.
