I was dead lifting on Wednesday (April 30, 2008), and I hit a PR on my 5RM. During the set and after the workout, my lower back felt fine. However, the next day, when I woke up, my lower back was feeling really sore.

I attributed this to a good workout, but the lower back soreness has plagued me since that Wednesday. I wouldn't exactly call it an injury, because it doesn't inhibit my lifestyle, but I would like to know what's up with my back?

Something which could be making this soreness even worse is that I have a very mild case of lordosis which could be aggravating my back. I'm very worried about injuring my lower back because I am currently 15 years old and 5'11", and I think I still have some growing to do!

It is Friday today, two days later. So far, my conclusions are:

1) The lower back muscles are still sore/stiff. They need more time to rest.

2) I might have messed something else in my back up....But what?

To solve this problem, I plan on doing some extensive spinal decompression after my workout today, mainly hanging from a pull-up bar and letting my body go limp.

Do you guys have any insights on my problem, or any suggestions on how to cure it?

Thanks a lot!!

Your spine is not the normal shape, so this may in fact aggravate the soreness you are experiencing. In addition, you are 15, they don't call it "growing pains" for nothing. You could coincidentally be going through those at the same time, further increasing the problem.

Stick to the rule of working out through the soreness, and if it starts to hurt, stop.

Honestly, if you're worried about it, you shouldn't be asking us, you should be asking your doctor or the staff at your sports medicine office at your school.

Make sure your form is spot on Form especially tends to break down when you are pushing the limits, they like to push back.

Congrats on the new pr, but avoiding and recuperating injury, especially at your age should be a priority.
