Back injuries can be extremely serious and may even require surgery to correct. Unfortunately, they can also be very common, especially after a rear-end collision. The force of the impact can cause the spine to snap backward, which can lead to herniated discs, nerve damage, and other problems such as damage to the muscles and ligaments or lower back injuries. The pain does not always occur immediately after the accident. Many find that the pain is delayed and not noticeable for several days. In some cases, the pain and stiffness may go away after a few weeks of rest and rehabilitation. However, in other cases, the injuries may be more severe and may require long-term treatment lasting months or years. In either case, it is important to see a doctor as soon as possible after the accident to ensure that you receive the proper diagnosis and treatment.
