Possibly. But an injured or degenerated spinal disc is just one of several prime suspects that can result in numbness in the foot or feet. Irritation of the sciatic nerve in your buttock, often caused by too much sitting or sitting on hard surfaces, is also on the list. There can also be local impingement of nerves in the lower extremity, and diabetes is also a suspect. Questions about your health history, your daily activities, your injuries, and an exam will help your doctor narrow down the list. Then further diagnostic tests, if needed, can be done to confirm.
