We don't do clinical advice here. If you have any problems that you have no answers for, you need to go to your GP to get it checked out. Sure we all suffer odd pains and problems with out backs, but the problem is, they are all so very different and occur for very different reasons. And much of it will disappear once we are up and moving. If it persists, then you need to get it checked out.
Seriously, the best thing for you to do is go to the doctor and get it checked out.
Sorry we can't help you with that.

So do all who live to see such times. But that is not for them to decide. All we have to decide, is what to do with the time that is given to us. (Gandalf the Grey)
I agree with Peter. Having it examined by GP n if required by ortho, can be your best bet. I suffer from sciatica which is usually a shooting pain, like electricity. I am currently under physiotherapy to resolve or control the same. It took me over 6 months to get diagnosed for it.
There can be numerous reasons for low back pain right from neuromuscular dysfunction to postural problems. Most low back pain is acute or short term, and lasts a few days to a few weeks. However, back pain that continues for weeks or months must get examined by specialist.
