ICE!! ICE!!! ICE!!!!! I just recently had my first back issue. I wasn't even doing anything. My back went "pop-pop".
Then...back pain. This was last wednesday, Sept 19th. I had forgot about the ice....went straight to heating pad. My bad. By the time I got to look it back up....it re-enforced the ICE. Get you some of those ice/col packs from Amazon, and use them. My pain has almost abated. Not even a week yet. I have been using them before bed, and then sleeping on it.
