Last year before my 2,000 mile Yellowstone ride I hurt my back, resulting in a bulging disc and sciatic nerve pain that plagued me threw out the whole ride, well a year later the sciatic problem is long gone, thank God but the disc is still their and I am staring a 3,500 mile ride dead in the face. The disc is not a big problem normally but this is a 10 day, quite a few miles thing, anyone had any success w/an over the counter back wrap/support ? Thanks in advance
