I am having and EMG or Nerve Conduction Study done on Oct 31. My problems started July of 07 when I was having chest pain and they Diagnosed with Chostochondritis. Then In Dec, I started to get lightheaded, numb and tingling sensations in my left foot, left hand and arm, my neck and the left side of my head, and shoulder blades, fluddering in my chest, heart palpatations, and ringing in my ears. They did a CT scan and MRI on my head to my seventh vertebrae, to check for MS and other possible problems. They found no problems on either test and diagnosed me with having Anxiety attacks. One morning I woke up and my middle finger, ring and pinky fingers on my left hand curled right up and it took all my strength to get them to straighten out, then as soon as I let up they curled up again, and I got this cold tingling sensation down my arm, this lasted for about 5 minutes. They feel the medication they put me on (Buspar), has the Anxiety Attacks under control but the numb tingling sensations are still there, so they decided to do this test. Is there anything in particular I should have the Doctors looking for with this test or anything that they might be overlooking?
