I've noticed after doing deadlifts, not directly after but maybe 12-24 hrs after, my lower back goes 'numb' after sitting for awhile.
Now I say 'numb' because that is what it feels like. I noticed it today getting out of my car after driving home from work and I pulled yesterday.
I can still feel my fingers if I poke it and pain if I pinch it, but my shirt brushing up against it feels 'numb'. That is the best way I can describe it.
I never notice it after squats and good mornings or olympic pulls, and its been going on for awhile while. I've gotten stronger since it started, so it hasn't affected my lifting, to the best of my knowledge.
I'm wondering if anybody else has experienced this.
Trying a pulled out of my ass diagnosis, it could be a pinched nerve, but the fact that the sensation is localized to the lower back is peculiar, and I'm not sure how a pinched nerve would effect gym performance. I'm thinking it hasn't effect my lifting at all, but I'm not sure a pinched nerve would.
Also, if I were to get this checked out, what kind of tests do you think will be performed. Since, it hasn't bothered anything or interfered w/ my lifting or daily activities, I'd prefer to not drop a bunch of cash on DOMS or something similar. If it will be cheap to get it checked out, I'd rather do that and not worry about having a messed up back later on down the road.
