Every time I go in an elevator, i come out feeling sick and headachey. Today I was in a shop and we went in the elevator because my grandma who I was with isn't very good with stairs. We only went up one floor but when I came out the whole room seemed like it wasn't really in time with me. When I walked, the floor felt like it was moving up and down and that I was moving with it. I felt like this for about 5 mins and then we sat down for about 20 mins. I thought it would have worn off or something but when I got up, I could still feel the same sickly motion. It carried on after I had left the shop for quite a while but then it stopped after a long time. I get this every time I go in an elevator. My grandma thinks its psychological but, I don't have any fear of lifts and I never feel claustrophobic, so why do I feel like this?
