I'm probably going to wait about a week with stretching, RICE, and some anti-inflamatories when needed, and then see if the the pain subsides. It isn't really too bad, just that I've never experienced any sustained back pain in my life before. I'm not sure how I injured it, but it is probably a combination of a lot of things. I bought a house recently and have been doing a few projects, also haven't had as much time for normal stretching and exercise lately. Just got a new mattress a few weeks ago and it may be causing some of the discomfort, although I've been sleeping really well on it. Lastly, I was on vacation for a week and playing lots of golf (a lot more than I am used to these days) and was also camping on an air mattress, but that hasn't given me any issues in the past.
Anyways, I've just been a little stiff in the morning and when twisting to turn off the alarm this morning, really noticed a sharp pain. With some stretching and hot shower, it subsided but it still feels a little tender.
Going to really focus on stretching and getting my core back in shape over the next few weeks. I'll put off disc golf for now until I feel I'm able to play again. Not that big of a deal for me, I can go months without playing and don't miss it a bit.
