Many people who have lumbar surgery find that it relieves their pain and helps them move better. You should be able to do most or all of your daily activities--driving a car, walking, sitting, and doing some kinds of exercises and sports.
The pain often decreases immediately, but recovering full strength and range of motion can take time. You need to be patient and stick with your rehabilitation plan. Even if you feel and move better right away, continuing your exercises and stretching is important. A stronger, more flexible back can help control your pain now and avoid problems later.
