Chronic Pain

Everyone feels pain at one time or another. Some pain may be short term and may need a mild medicine or no medicine at all, or it may go away on its own.

Chronic pain is different from pain that you have once in a while. Chronic pain is pain that continues when it should not, it lasts longer than normal healing. It is pain that might last for months, and may persist or recur for years 1,2.

Over 100 million Americans suffer from chronic pain1. Common chronic pain complaints include: headache, low back pain, cancer pain, arthritis pain, neurogenic pain (pain resulting from damage to the peripheral nerves or to the central nervous system itself), psychogenic pain (pain not due to past disease or injury or any visible sign of damage inside or outside the nervous system)3.

If you think you may suffer from chronic pain, you should talk to your healthcare professional.
