Neck pain is actually the first sign of a condition called disc herniation in the neck. Low back pain is actually another first sign of lumbar disc herniation. In fact, one person in every three will suffer from back pain at least once during lifetime. This pain can be acute, that is, it can suddenly start with all its intensity; or it can be chronic, i.e. it can be seen as a recurrent or repetitive neck pain. This can last up to several days and usually ends with a little rest or spontaneously. Sudden onset is usually due to a wrong movement; it is like a kind of sprain. Moreover, neck pain may be caused by a mental illness such as depression, a heart disease or shoulder joint problem. Therefore, it is necessary to have an examination by an experienced doctor.
Pain is not actually your enemy, it is your friend. It reminds us that something is wrong. Therefore, you should not use painkillers more than necessary; they do not heal you but only stop the pain, that is, silence the alarm which is ringing. If the severity, duration, and frequency of your neck pain are increasing and the pain radiates down to your arm or up to your head; then you must immediately find a permanent solution.
