Why Sciatica Muscle Pains Occur. Both the piriformis and the sciatic nerve begin at your tailbone (coccyx). The piriformis crosses directly on top of the sciatic nerve, and this is what causes the problem. When the muscle goes into a spasm it presses down directly onto the nerve, pushing it into the bone underneath. And you get the terrible pain of sciatica.
Low blood pressure. Low blood pressure occurs when blood pressure is much lower than normal. This means the heart, brain, and other parts of the body do not get enough blood. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg. The medical name for low blood pressure is hypotension.
