true beer will help, it always does lol!!!! but seriously if it is a muscular problem the hot and cold will sort it. heat increases mobility and relaxes the muscles giving you alot more in terms of flexion and rotation of the spine, while the cold is an analgesic which will reduce pain, any swelling and help with reducing muscle spasm. you gotta be careful man you shouldnt really be suffering with back pain at 24!! also i think alot of lifters should have regular (monthly) massages to help iron out any knotts, tension and just generally relax there muscle, there are loads of studdies the suggest that massage can actually help stimulate balanced and even growth in bodybuilders
