Y'know, I kinda feel bad that your back is hurting and you posted a serious question asking for help and all you got was a typical RCMB smart ass response that wasn't funny at all....
I don't know about devices, but I've had lower back problems in the past, and the thing I've found helps the most is strengthening it in the gym, my favorite exercise specifically is the one below. FWIW as your lower back gets stronger, it helps to hold a plate behind your head or in your arms. It has helped reduce the frequency and severity of these episodes big time. In fact I haven't had any real problems in a number of years. If this doesn't work, vicodin and skelaxin or valium will help. Good luck.
