When we think of what might cause pain, nerves are often forgotten.
We have hundreds of meters of nerves, and neural pain is far more common than we think.
We have all experienced irritating a nerve in our lives. This happens when you hit the side of your elbow. Thousands of nerve fibers react to this mechanical stimulation, and we can feel sensations running all the way down to our little finger.
Anatomically, a nerve is a chord. Half of it is a thick ligament which makes it strong, while the other half is neurones which inform the brain or drive muscles.
Danger sensors are found in both parts. They will react to mechanical stimuli, lack of blood or stress chemicals.
Nerves slide as we move. Injuries that alter this movement may lead to movement related.
Not every nerve damage appears on MRI.
A nerve is usually irritated mechanically by pressure or stretch.
