L5 innervates the side of the thigh and lower leg, as well as the top of the foot and big toe. In case of irritation, numbness or weakness is felt thumb up. The clip places this within “Neuralgias in the legs” so it is easier to understand what is happening in the area, not only where symptoms are felt.
Nerve-related symptoms are not always felt where the irritation begins. The visual shows a possible symptom pathway, while movement, strength and sensitivity still need to be assessed in the individual person.
This is an educational visual linked to “Neuralgias in the legs.” If symptoms keep returning, restrict movement, or their source is unclear, a functional assessment is a more useful next step than guessing.
