Not 100% sure if this applies to me but this week have sucked as far as back pain goes...did drywall on Monday, no pain. Installed an interior door on Tuesday, no pain until about 2 hours afterwards. I've been in pain since. ibuprofen or Tylenol doesn't seem to help a whole lot, but a hot shower does. I'm in pure pain in the morning(almost impossible to get out of bed and get dressed) but after moving around a bit and a hot shower, the evenings aren't too bad.
This may sound strange, but with the disc issues I have in my neck as well as lower back, sleeping position can make a big difference. For lower back, laying flat on my back with a pillow under my knees has helped (elevate legs a bit to take some pressure off). With the more recent issue with my neck which showed some extrusions of the disc material, etc, I have found that also laying on my back with not much if any elevation of the neck, but turning my head to one side has helped quite a bit.
Bottom line, look for a sleeping position that helps and you may be amazed that you can maintain that position for a good bit of the night and may feel better when you wake up in the morning.
Depending on where the pain is (upper, lower, middle), there are some different movements and low impact exercise movements you can try that help alot as well.
