Muscle cramps at rest is almost always due to superficial venous insufficiency. Abnormalities of circulation during this condition result in a "contamination" of the muscles with end-metabolites, such as lactic acid and the like. When our body is reclined or in horizontal position, such as during driving or at night, venous circulation of the lower extremities becomes near normal. At this time, our muscles develop a very low threshold for contractions, where even small movement can trigger a prolonged and painful spasm (leg cramps), typically referred to as "cramping", "Charlie horses", etc. Interestingly, the isolated contractions of individual muscle fibers, often perceived as a crawling or "running water" sensation (called "paresthesia"), is due to superficial venous insufficiency as well.
