Piriformis, also called the pear-shaped muscle, may be behind abnormal buttock or pelvic pain and you clicked on this video because you want to determine which is the cause of the symptoms. Absolutely great, because this information package is surely comprehensive and with the instructions in this video you can easily test at home which one is the cause of the trouble. In piriformis-related symptoms there are certain specific characteristics and in ischias nerve symptoms there are also typically their own small particles. How do these differ from one another?

You will get the answer in a moment, but first we slightly need to understand anatomically how these structures travel in our body. Let's start by locating where the pear-shaped muscle resides. When you place the tip of the finger in the outer surface of the thigh, you should feel kind of bony lump. That is the greater trochanter of the femur.

When you are at the upper edge and slightly backwards, the fibers of the piriformis muscles are located and the muscle body originates from the anterior surface of the sacrum, so roughly from S2 to S4 level. The sacrum has its openings and at each opening there is an individual level and this is how the naming of the origin comes from. The sciatic nerve, on the other hand, is the largest single nerve in the body, originating from the fourth vertebra of the lumbar spine down to the third level of the sacrum. From there, it continues along the back of the thigh and branches into multiple smaller nerves before the kneecap.
