I have read complete details of your question. It looks from your details that you are having backache which is troubling you. If biopsy had not shown any tumor or TB then you should not worry. Such type of pain in your age can also be there due to infection of disc or abnormal posture. There are several other reasons like Schumann disease, previous trauma leading abnormal strain over the vertebrae. At present, you should take care of your posture should avoid abnormal strain over your back by avoiding abnormal bending. Learn some exercises for your back which does strengthen your back muscles- Do these exercises only under supervision recommendation of your orthopedic doctor. Hope this all will help you. With best wishes.
