Hey there Kit Kat!!
Welcome!!! I have a really bad back, I fell of a 3rd floor loft in a barn when I was 21, I hit my tailbone on a spigot (sp) and shattered it, my tailbone, not the spigot (lol). As time as gone by, I'm 51 now, my lower lumbar disks have all herniated or are buldging. So, I know a little about the subject.. LOL. My best advice is go on line and look up back stretches for the specific area of your back that hurts. Don't lay around too much it will only make it stiffer. Go to your doctor and tell him/her what's going on and if you can you'll need PT. That will make a big difference in learning how to live with a bad back. Another thing.. depending on what part of your back is acting up, the way you lay in bed is really important, so look that up on line too. Since mine are in my lower back, if I lay on my back I have to keep my legs elevated. If I lay on my side I need to put a pillow between my legs. Laying completely flat absolutly kills me!!
Anyway best advice.. go to the doctor as soon as you can. It could be something serious!!!
