I've recently been feeling the same way and have been looking it up excessively online because it doesn't seem normal. Here's what I've learned:
1) You should not force your back to pop. It can lead to scoliosis and other back issues later in life. If your back truly needs to pop it will pop on it's own.
2) You're not actually realigning your back. If you think you are it can lead to an obsession with popping your back when it's in your head and your back doesn't need to pop.
3) You should see a chiropractor if you're not forcing your back to pop and it pops constantly with typical movements.
4) You need to fix your posture if it's bad.
5) Try laying on the floor with your legs bent over a chair to relieve pain rather than popping your back. It helps a lot.
6) Put a pillow under your back when you sleep as it can relieve pain due to sleeping weird.
Don't know if that helps, but I hope it does.
