I have a similar story, but not as serious as OP. A couple years ago, out of the blue, I started having almost constant unbearable back pain. Doctors I saw didn't know what it was. Eventually, one of the neurosurgeons, after I showed him an old MRI scan told me it was a cyst in the spine that was 80% of the time asymptomatic and unlikely to have caused the issue. That cyst required surgery and only 3 doctors in the world have done it before. During this time I started to go to the gym and train, and after some time, the pain went away on its own. Not sure if it was because of the better food I was eating or stronger back muscles that got rid of it. Since it's a neurological issue, some postures and chairs still cause pain, but it usually goes away quickly now.

Same here, 14 years lifting, suddenly I had to be in bed for back pain for a week. After that I spent 4 years with backpain and stopped training following the advise of various doctors. Met a guy who does power lifting, we became friends, he is also a phisio and told me to gradually go back to the gym, pain almost disappeared after 6 months. Now I am almost back to lifts I used to do 20 years ago, but I manage pain actively and avoid overdoing it. Most doctors don’t train and don’t understand how mind/body works. Sometimes pain is not linked to a “real” physical problem, then you do MRIs, talk to doctors, and they find a problem somewhere, they always do, but it could have nothing to do with the pain.
