The best test would be an EMG/Nerve conduction study. This needs to be performed by either a physiatrist or a neurologist
I have been suffering from back pain because my job requires me to sit for long periods of time. Do you think medication will help me?
It is most important to stretch on a regular basis, and perform core strengthening exercises. Proper ergonomic work station should be assessed. I suggest following these recommendations before starting any medications. Keep in mind, drugs have side effects, and many pain pills are not meant for long term use. If you are experiencing pain, numbness, tingling or weakness in your legs, you should see a specialist. Speedy recovery.
