Sir, my father got a brain stroke one month ago, because of this left leg lightly paralyzed, taking medications but from the past one week his voice is completely changed, feeling difficult in talking. Neurologist doctor saying that sugar is the reason for voice change( now sugar is 280). My doubt is voice change is for sugar or blood clotting in brain? And my father says still leg heel pain in bottom only on left leg and left hand? Please give suggestion...
