Diagnosed with idiopathic sensory-motor nueropathy 2 months ago.I have had odd feelings in my right foot for a couple years. Now both feet get tingling sensations in them, weakness in both legs, left knee sometimes feels like it wants to give. I am 41 and the doctor said it is not a common finding in someone my age. I'm not diabetic, no thyriod problems, I'm not an alchololic. All my labs for common causes came back normal. He said sometimes it improves on it's own so he is going to do another NVC test in 10 months to see if there is improvement or worsening then we will go from there.
