Deadlift Pain

First off, I deadlift fairly often and can generally differentiate between “good pain” and “bad pain”.

I was doing some 5x5 deadlifting today, and around 5 minutes after the completion of my last set, I experienced lower back pain that brought me close to tears. I lay down and waited for a further 5 minutes, and the pain resolved and has not bothered me since.

It felt like an extremely intense backpump, but I’ve never had pain this bad before. This can’t be right, can it?

Any loss of feeling or numbness in either leg?

Nope. Are you thinking Sciatica?
