I have the same problem, except I've had it for about 3 years. Strech it out(I'm sure you can find one that works on the 'net. It's hard to describe.) Heat packs can help before you do anything, and use them afterwards.
Depends what kind of back pain you have... if its muscular, then some of the ideas here are fine, however, after a workout, I would use ice, not heat. Stretching before and after is huge. Sounds like you might have to do some training to strengthen your core.
However, if you are not sure whether or not it is muscular, you should see a doctor.
I had back surgery last November.... I had constant pain and when I finally went to the doc, he sent me to a orthopedic specialist. After physical therapy did not work, they did an MRI and found I had a herniated disc, which I believe I got from a mountain bike accident. Anyway, I had a surgery to address it and I am doing much better now, but still working on building my core back up.
So, if its chronic and wont go away, my suggestion is to go see a doctor.
I had the same issue a few years ago and I traced it to my bed. It was way too soft and I wasn't sleeping flat. A bed should be comfortable but firm...
i have some back problems too, i think it is a combination of improper lifting for a little while before i corrected it, my bed which totally sucked, and overall bad posture...that and i got rear ended twice in 2 different cars...i've been going to a chiropractor for a while and it has helped a bit, but not significantly enough...i'm to the point where i am probably gonna go see a doctor...so yeah as they said, keep an eye on it and don't let it get too bad before you do something about it...better to be overly worried than let it fester and turn into a surgery situation...
Its stays in my lower back. I think It might be from straining when lifting but I will stop doing anything that aggravates it.
I've got the same problem but it's not from weight lifting. I got it from landing awkwardly when doing the triple jump. I went to the docs about it and he sent me to a physio, she then told me that because I have damaged the muscle on the left of my lower back that the muscle on the right of my lower back has strengthened to compensate for the damage. She then gave me a bunch of stretches to try and stretch it out and other stretches and excercises that would strengthen other parts of my body (Abs, Quads, Hamstrings etc.) that would help relieve/work out my back pain.
