What are the causes of chronic pain
Causes of chronic pain are unclear. When you have an injury or illness, certain nerves send pain signals to your brain. In chronic pain, these signals continue to go for weeks, months or even years after you'll get well. Chronic pain can develop after a serious injury or illness, such as for example a back injury or shingles, or may overtake you for no apparent reason. There is also a possibility that certain brain chemicals that suppress pain, cease to operate normally.
The pain may be:
- Neurogenic pain, or neuropathic pain,which occurs when damage to the peripheral nerves or the central nervous system. Pain nerves are causing themselves and the pain of this type may not respond to treatment as expected.
- Psychogenic pain, the cause of which may beemotional or mental aspects. The cause of this pain is not a disease, injury or damage to the nervous system. Psychogenic pain is not common, but the stress, depression and other mental health factors can increase the pain.
- Unidentified pain. It may be that the cause of your pain can not be found or identified. Analyses and studies may not show any injuries, illnesses or changes in the soft tissues, which could become the trigger of pain.
What are the symptoms of chronic pain
