MP is only the involvement with the lateral femoral sensory nerve.

It does not cause diffuse leg pain or aching, is rarely bilateral (but can be) and should not cause pain during defecation. MP pain is typically sharp, lancinating, and confined to a specific area of the thigh. In between sharp, can be numb tingling etc. I liken it to 100 bee stings all once. Another person described it to me like a lightening bolt. Stretching the leg, extending the leg, often brings on a stab. If your legs are not the same length, you can get this too, when the shorter one overextends. There is typically no weakness or change in ability to walk (except from the pain aspect).

Sometimes the term gets loosely applied to "thigh" pain. But it does not affect muscles in the thigh. Muscles do not get "weaker" or fail.

Hip pain, groin pain (hernia), back pain/disc issues, there are many other causes of thigh pain.
