While playing football, Ramn is tackled hard, and as he tries to get up, he finds that he has difficulty flexing and adducting his left thigh and extending his left leg. Which nerve innervating the lower limb may be damaged, and how would the damage affect sensory perception in Ramn's left leg?

Answer to Question 1

Ramn has a damaged left femoral nerve. This nerve also supplies sensory innervation to the skin on the anteromedial surface of the thigh and medial surfaces of the leg and foot, so he will also experience numbness in those regions.

Answer to Question 2

The symptoms include red skin that is warm to the touch. The skin is extremely sensitive and very painful. Additionally, the skin forms painful blisters that are slow to heal. The rash follows the dermatome of the affected sensory nerve so it is typically a small area and usually affects only on one side of the body.
