If that occurs in an autoimmune disease context I would think it might be caused by polymyositis. I'm sorry to hear about the abnormal muscle response. Anyway, that's just to say that you shouldn't rule out neuropathy as the cause for your numbness. I'm not sure whether it matters to you or not, but there are other tests that can try to diagnose SFN like a skin/nerve biopsy. However, if your numb calves are being caused by a small fiber neuropathy, then this will not be evident on the test. Usually the NCV/EMG is trying to rule out these diseases as causes for things like tingling/weakness/numbness/pain. Basically when a neurologist orders the NCV/EMG they are trying to determine whether you have an identifiable neurological disease causing your neurological symptoms. You can have a 'normal' response from your nerves on the NCV/EMG and still have small fiber neuropathy which is the sort of neuropathy more common to people with autoimmune diseases anyway. Well God Bless and hope you get some answers.

with cardiolist on Monday and when I go to Charleston in Aug. Now I recently had a cardiac catherization due to shortness of breath and thankfully they found no blockages but did say I am in early stages of pulmonary hypertension. I was diagnosed in 2009 although had Raynauds symptoms and other syptoms for a few years before that. This disease really knocks the hell out of people. I am on several meds a day and just have to suck it up I guess. All I know is I am in pain most all the time. My ruemotologist does not agree but another second opion neurologist agrees with the other ones findings. The neurologist found and article from Mayo Clinic about experiment they did on over 500 scleroderma patients with neuropathy and found they had no other physical reason to have the neuropathy except the scleroderma. Neurologist feels it is related to Scleroderma. It flares up and I have some really bad days often. Eventually I may try to take it daytime as well.

I take it only at night though because it gives me blurred vision and some dizziness although that seems to be getting better. Was on Prednisone for about a year and it helped the pain until I got down to 10mg and no relief from smaller dose. After the test I was diagnosed with severe sensory motor neuropathy in all four extremities. I acturally have tripped and had several falls. My legs felt so heavy and I had to concentrated lifting my foot to walk. I had EMG last year because I was having severe pain in my legs and arms.

Emg test does it hurt
