Tingling sensation and Blurred vision.

On 4th July night I experienced tingling sensation in my left hand smallest finger and the ring finger. I Shook my hand and did some movement in shoulder and arms and it went away. The next morning when I woke up I felt the tingling sensation again at the same spot. I was looking at my mobile and felt that there was some sort of blurry ness in my right field of view. I closed my right eye the view was clear but when I closed my left eye, I had blurry vision. Probably this there from before but I noticed it yesterday. So I thought maybe due to anxiety this issues were coming up and I found that I was unable to sleep as I was fearing that this tingling sensation will again come back. After some time the tingling sensation was all over my body sometime legs sometimes hands, sometimes knees etc. But it will be like 2 seconds tingling and then never on the same spot again. So night came and I when I woke up i felt that my i cant feel my left ear. But now again it is back to normal.
