What could be causing pain, itching, and numbness in my left thigh, along with knee pain?
Your symptoms, particularly numbness and itching in the thigh along with knee pain, may indicate a compressed or irritated nerve. Common causes include arthritis, muscle strain, a slipped disc, sciatica, or meralgia paraesthetica (a condition affecting the nerve that supplies sensation to the outer thigh). You should consult your doctor for a proper examination and appropriate treatment.
