Sometimes I watch youtube videos of people getting their backs cracked, and dream it was me. My back does not crack EVER and I am constant pain. Sometimes I’m in so much upper back pain I feel like I’m going to throw up! I hate it. I try to sit and twist to crack my back. Nope. I try to use a basketball nope. I have had other people try nope. I’ve gone to professionals NOPE! I’d paid for someone to walk on it. Just to not feel pain anymore. IT S****.
