I occasionally have slight numbness in my hands, arms, legs and toes. My extremedies fall asleep easily. Sometimes I wake up feeling like I am trembling inside. I do have back pain and sometimes I feel pain in my legs from that, but the numbness is happening in my upper body too. I am in good health otherwise. I am 68 years old, female, 5 2 tall, weighing 140 lbs. I am still working at an office job, but I am relatively active. I have high blood pressure, chlorestol and acid reflux, all treated by medications. I am concerned I am having heart issues or could have a stroke. I live alone and am feeling anxious about the numbness. Please advise.
