Not fun, you need to literally baby yourself back to health. The last time my back got shot it took me 5 days to be able to walk again, it took another 2-3 weeks before I could squat down to reach the floor.
Ice Ice Ice & more ice. To the point it will drive you nuts. Heating packs too, but more ice then anything. I remember it took me literally 15min to wobble (0.5" at a time) to my room from the garage (like 40ft) it sucked, bad. The best I can describe that pain is literally a knife in your back.
Hope I never have to feel that **** again. You need to go back to the chiropractor, and do NOTHING but Ice it and rest. Once you have your mobility back, from that point on, take is s-l-o-w. I wouldnt even think of thinking of going to therapy until 2-3 weeks AFTER you gain the ability to finally pick something up off the ground again. Take it at your own pace, if you think its going a bit far, it probably is.
The best I can describe coming back from a back injury is, climbing a long stair case. You cant go too fast though, because the second you go too fast, the steps pull in and you slide back down to step #1 again. Take your time, you dont want to end up at step #1 again.
Ive always heard good things from doing reverse hyper extensions for your back, I've never had the luxury of finding a gym with one though. I've thought about ordering one, lol.
