Woke up and had some pretty intense vertigo. Almost like I was drunk where everything would swing to one side. Called the oncologist and he said to go to the ER. So I went to the ER and after the docs and a PT looked at me they determined that a crystal in my ear was out of place. The PT did some exercises with me to get the crystal back in place and everything more or less went to normal.
Made my preferred language Klingon in the hospital. They got a kick out of it.
