Have you changed any of your medications?
Just a side note - my brother is a doctor (a GP) and we happened to be standing right there when that kid fell from the bamboo sculpture. I saw the kid fall out of the corner of my eye because I had turned away and didn't want to witness the stupidity. I immediately turned to my brother to see if he was going to intervene. He was already there by the crowd but just watched. He saw that the guy was talking and conscious and didn't feel it was necessary to involve himself. I thought that was interesting.
Anyway . . . I hope you feel better real soon, Ivy.
