this past few day i have been feeling dizzi. I feel like everything is moving in circles. Now there was this time when my hand went numb and had a hot flash at the same time. this happened for about a minute. After that I have now started to fell numbness for a few seconds on my arm and sometimes in my fingers. But some times i am having pain in different parts of my left arm. They have told me that probably is my colesterol. Can this be causing this problems?
