In addition to the sciatic nerve, many other nerve roots in the lumbar spine transmit nerve signals to the legs. Therefore, a bulging disc at any point between the five vertebrae of the lumbar spine (L1 to L5) or between the bottom of the lumbar spine and sacrum (L5 to S1) could result in leg pain.
Ipod nanos last about a good 12 hours on a fully charged battery. The time varies depending on how often you stop it from going on continuously.pod nanos last about a good 12 hours on a fully charged battery. The time varies depending on how often you stop it from going on continuously.
I also have several iPod models (2 2nd gen nanos, 1 1st gen nano, 1 shuffle, 1 30 GB Classic, and a 3rd gen iPod Touch). Since the Touch is only 1 day old I can't say how it will hold up, but all of my iPods are still working, although the 1st gen nano has horrible battery life at this point. All of them are at least 2 years old.
