`what causes your tailbone to hurt`	A coccyx injury results in pain and discomfort in the tailbone area (the condition is called coccydynia). These injuries may result in a bruise, dislocation, or fracture (break) of the coccyx. Although they may be slow to heal, the majority of coccyx injuries can be managed with cautious treatment.ost tailbone injuries are caused by trauma to the coccyx area. 1 A fall onto the tailbone in the seated position, usually against a hard surface, is the most common cause of coccyx injuries. 2 A direct blow to the tailbone, such as those that occur during contact sports, can injure the coccyx.	`1.0`
`what muscles do trunk lateral flexion`	`Itâs the same with the External Obliques, but unlike the External Obliques, they are not visible when fully developed. Action: 1 Supports abdominal wall, assists forced respiration, aids raising intra-abdominal pressure and, with muscles of other side, abducts and rotates trunk. 2 Contraction of one side alone laterally bends the trunk to that side and rotates the trunk to the other side.`	`0.0`
`brake horsepower definition`	`When the brake lights will not come on, the first thing to check is the third-brake light. If it too is not working, the brake-light switch, a bad fuse or an unplugged harness is likely.ull up on the brake pedal and if the lights go out, switch mis-alignment or pedal position error is the likely cause. The final possibility is a wire shorted to power. Unplug the brake-light switch and if the lights stay on, a short circuit is the case.`	`0.0`
