Intermittent vascular Intermittent vascular (or arterial)<unk>  (Latin:<unk> intermittens) most often refers to cramping pains in the buttock or leg muscles, especially the calves. It is caused by poor circulation of the blood to the affected area, called peripheral arterial disease. The poor blood flow is often a result of atherosclerotic blockages more proximal to the affected area; individuals with intermittent<unk>  may have diabetes — often undiagnosed. Another cause, or exacerbating factor, is excessive sitting (several hours), especially in the absence of reasonable breaks, along with a general lack of walking or other exercise that stimulates the legs. Spinal or neurogenic Spinal or neurogenic<unk>  is not due to lack of blood supply, but rather it is caused by nerve root compression or stenosis of the spinal canal, usually from a degenerative spine, most often at the "L4-L5" or "L5-S1" level. This may result from many factors, including bulging disc, herniated disc or fragments from previously herniated discs (post-operative), scar tissue from previous surgeries, osteophytes (bone spurs that jut out from the edge of a vertebra into the foramen, the opening through which the nerve root passes). In most cases neurogenic<unk>  is bilateral, i.e. symmetrical. Jaw Jaw<unk>  is pain in the jaw or ear while chewing. This is caused by insufficiency of the arteries supplying the jaw muscles, associated with giant cell arteritis.
