Your doctor can rule out certain medical conditions that may be the cause of the neck and back pain. It may require comprehensive physical examination and diagnostic testing if deemed necessary.
If there was no obvious injury, the pain could be muscular in nature from overstraining, or it could be the result of disc disorder. Either way, physical therapy may be prescribed to condition, stretch and loosen the neck and back muscles to relieve the pain.
When the herniated disc ruptures and pushes out, the nerves may become pinched. A herniated disc may occur suddenly, such as with a fall or an accident, or it could happen gradually with repetitive straining of the spine. This may lead to you developing weakness and or numbness in a specific nerve distribution. Both conditions should be assessed by a physician.
