Thus a small animal can lift many more times its own body weight than a large animal, because as the size of an animal increases, its muscle strength increases by length2, but its body weight increases by length3.
Symptoms of trigeminal neuralgia. The main symptom of trigeminal neuralgia is sudden attacks of severe, sharp and shooting facial pain that last from a few seconds to about two minutes. The pain is often described as an excruciating sensation, similar to an electric shock. The attacks can be so severe that you are unable to do anything during them, and the pain can sometimes bring you to your knees. Trigeminal neuralgia usually only affects one side of your face. In rare cases it can affect both sides, although not at the same time.
Pain may involve any of these locations but usually involves the second or third divisions, either alone or in combination. Trigeminal neuralgia may involve the first division but usually in association with the second division. Pain in only the first division is often not trigeminal neuralgia. back to top What causes Trigeminal Neuralgia? The trigeminal nerve carries messages regarding sensation from the face to the brain. Patients with Trigeminal Neuralgia have a defect in the covering of the trigeminal nerve, which allows abnormal cross-talking between nerves that usually carry messages of normal non-painful sensation with nerves that carry painful messages.
