I am a type 2 diabetic. My a1c was last checked in Feb or Mar 2015 was 5.6. The left side of my body is weaker then the right. My legs feel fatigued and heavy after walking about 20 minutes. An emg test was performed in March that indicated that there was muscles like my quads were not receiving signals as they should. No doctor has told me what is wrong. I have had this weakness in my left side for about 5 years.
