I noticed a slight pinch after my workout tonight. It's about 3 inches up and to the right of my tailbone. Right above my right a$$ cheek. It's not bad I can walk, run etc. but notice a slight pinch when bending at the waist ...especially when standing back up from bending at the waist. Also I did not feel any injury while lifting but rather when I got home.

Anything I need to watch for on my form? I thought I was doing well keeping my form in check but obviously not.

Thanks
