fusion surgery for localised back pain is offered only when a MRI reveals a degenerated black disc. You would like to know that even after a successful procedure 20-30% patients still continue to have some degree of back pain. This is because there are many causes that contribute to pain and surgery can take care of only a few of them. Typically the pain from a degenerated disc leads to pain during sitting for long , standing for long , changing positions etc.
Next Steps
I would strongly suggest you to modify your lifestyle and avoid movements that aggravate the pain. Do not lift weights more than 5 kgs, or sit on the floor. Avoid bending too much. Try yoga , physical therapy , acupuncture . If your pain persists and you are getting dependant on pain killers then only consider the surgery. Hope you find this helpful.
