Over-the-counter pain relievers, such as acetaminophen (Tylenol and others) and ibuprofen (Advil, Motrin IB, and others), can often control mild to moderate whiplash pain. Like any other injury, rest can ease the symptoms of whiplash. A few days of bed rest can help you recover. However, excessive lack of movement can delay recovery.
Neck structures may weaken due to prolonged immobilization. The doctor will tell you how long you should rest and any movement restrictions you should follow. Rest may help for the first few days after the injury, but you'll need to be active to complete your recovery. Being inactive for too long can be harmful.
Muscle stiffness and decreased physical strength are typical problems for those who have suffered an injury and have been at rest for a significant amount of time. To combat this, your doctor is likely to incorporate light exercise or physical therapy into your treatment plan.
