breaking off in your carotid artery
will travel into your brain and cause a stroke
. The sciatic nerve is a large nerve in your buttock region, formed by union of multiple nerves roots originating from the lumbar spine
, and under normal physiologic conditions will not be affected in any way by a thrombus in the carotid artery. Sciatic nerve pain
is usually caused by a compressive lesion (i.e. a disc herniation in the lumbar spine). In order for a thrombus to go from the carotid artery to the buttocks, it must first flow down your neck (against the flow of blood), into you aorta, and into your pelvis. Even then, it will not compress or cause "pressure" on anything since it will stay lodged inside a branch artery and obstruct it.
