welcome buckowens, and i have broken my back, and also have herniated/ruptured disks in my lumbar and cervical. so yes, hammock is the way to go. never felt better since i returned to backpacking after being told i had to give it up!and like justfeff mentoined, there is a learning curve. i use a top entry hammock and i think its less of a lerning curve for it(just my opinion.
