I had prolonged stress for a couple of years end eventually while walking, I started feeling as if my right side were falling off. I would feel funny on my feet and then lose my balance. I drifted on my left side could follow. At times I was lightheaded, and felt as if were floating. My blood pressure was 160 and I was put on drugs. Even now the feeling is still there and mostly I feel it on my right side of the head above the ear. What could this be?
