I have had a sudden onset today of my left side of my body being numb and weak. From my face down to my leg. I have been noticing sudden vision changes. It's gotten really blurry and I'm having double vision. I am dizzy and I did pass put two days ago. I get migraine headaches sometimes but the numbness I get with those goes away quickly. This time it isnt. Should I be worried or go to the ER?
