In general, you should be able to resume normal activities. There are many factors that determine the extent of physical activity and your doctor will discuss these with you. Your spine plays an extremely important role in every aspect of physical movement. The surgery you have may restrict movement or not, and may require that you lift lighter weights than before. Each individual, and their adherence to doctor’s care notes and therapy, will have a different outcome. Work with your doctor and let him know your level of expectation after surgery. He will work with you to educate you on your condition, surgery, and expected outcomes, and create a plan that is realistic and achievable.
