What causes chronic pain?
There can be several causes of chronic pain. However, there are certain ones that are the most common.They include headaches, backaches, joint pain, and injury pain. However, these aren’t the only sources of chronic pain.
There are other types including sinus pain, tendinitis, and carpel tunnel syndrome. There’s also chronic pain that affects certain body parts. That includes the shoulder, neck, pelvis, nerves, and so on.
Chronic pain often starts with an initial injury/trauma/infection. Sometimes there’s a continuous cause of pain. There are many people who suffer chronic pain even though they didn't experience any past injuries or physical damage.
One effect of chronic pain is that the body sometimes produces more natural painkillers. That can result in negative feelings that boost the body’s substances that increase pain sensations. That can cause a cycle of pain that the person experiences.
This can even affect some of the body’s most important defenses such as the immune system.
