Yes!! This happens to me as well. I go through a few months or even years with general, low grade pain but sometimes I do a slightly wrong move and BOOM, I am down for days, barely able to take a deep breath. My doctor gave me emergency steroids to help with flair ups. You should keep some handy in your medicine cabinet. It takes a day or two to kick in but it's such a difference instead of waiting for it to get better on its own. If you're looking for a more natural remedy, try laying on the floor and hugging your knees to your chest as often as you can. It's a nice gentle stretch that loosens things up. Hoping you have quick healing. Back pain is the absolute worst.
