Today I was deadlifting and as I pulled up the weight it felt like someone punched me right on my tailbone and it popped. I was able to finish the lift, but the left side of my lower back felt strained. I did some light t-bar rows and it didnt feel to bad and then I did a few lat pulldowns, no significant pain while doing those. But when I twist I feel the pain. It is not terribly intense just uncomfortable. I decided to go home and ice it as well as take a hydrocodone. I was wondering if anyone has had this happen to them before. I will probably try to go back to the gym tonight to finish up my workout, just go lighter. Anyone had a similar thing happen?
