I have been having symmetrical numbness in my legs since April: front and inner thighs, inner knees, calves and bottom of feet. Progressed gradually from feet to thighs. No improvement over past 4 months. Some muscle wasting and weakness. Affects my balance and walking. Neurologist says MS because there are brain and spine lesions. But no optic neuritis or L’Hermitte’s. Other body parts not affected. Any ideas? Peripheral neuropathy?
