I am a 36 year old female. I have recently been experiencing heaviness in my left arm. At times my hand does not seem that it's "working" right. Along with this, I have light headiness at times as well as tingling in my left cheekbone and the back of my head with some pressure behind my eye. All on the left side. I went to the ER and they took a CT scan of my head, a chest xray and blood work I guess to make sure I wasn't having a stroke/heart attack and found nothing. Any ideas?
