A rhombus is a quadrilateral with all 4 sides being the same length. For example, look at the chopped-off pyramid on the back of a U.S. one dollar bill. The front face you see under the eye is a trapezoid, since it has 4 sides, and the top parallel with the bottom. A square is one example of a rhombus, but you can have a rhombus that isn't a square.
Causes of Trigeminal Neuralgia. In many cases, the cause of TN is never found. According to the National Institute of Neurological Disorders and Stroke, although anyone can get TN, itâs more common among women than men. Itâs also more common in people over the age of 50, although it can occur at any age.
What are the symptoms associated with Trigeminal Neuralgia? Pains are brief, lasting from seconds to a couple of minutes. Attacks of repeated brief bursts of severe pain may occur and last for an hour or more. Pains are usually shooting, stabbing, sharp and electric-like. Pains are usually triggered by light touch such as talking, eating or brushing the teeth. Pains are located in the face, usually in the cheek, lips, jaw, palate, tongue, teeth, gums, side of the nose and, less often, about the eye and forehead.
