Yes, it's possible in some cases. In some cases, you might need an operation. Or may be a better doctor. When I was young, I had back pain when I bow/go down. It came suddenly and stayed for more then 2 years -> 2 years of not being able to get things from floor without pain. My doctor here (one of the best in town, Germany), did X-ray, analysis, X-ray, decided to prescribe medication that I can't take. Then he wanted to make an operation, which I didn't want. So, after 2 years of pain, I went to study abroad in China. There, I went to military hospital and ask a guy what could that be, what I have. I didn't tell him the diagnosis of the German doctor. So that Chinese doc looked at me, make me wait outside for 5 mins and when I went in back - really funny story - he took a pencil and with it pulled up my shirt, asking me whether I wear a trouser belt, which I don't do. After I say "no", he told me to pull up my trousers. Suddenly, I felt a light relief of pain.. and I tell you, the next 1 week I always pulled up my pants and the back pain never came back again. Since 20 years now.
So, your tip with resting is exactly that what is needed. But I don't know, whether all conditions can be healed by that, or some still needs medication or operation.
Good luck to all and always pull up your pants!
