I've had pheripheal neuropathy in my feet and lower legs for about 12 years, all of a sudden this morning I awoke with pain in the back of my knee and thigh that almost feels like a neuralgia only it hurts more, Its a burning and its really sesitive to the touch, and growing worse as the day progresses. Does this sound familiar to anyone? I'm a non-insulin dependent diabetic with cad and some pad and heart disese. Thanks for any help-What is this??
