Kathy - I'm very sorry you've had such a painful, difficult "bout" - I hope it's over - never to return.
In Feb. I had surgery that caused some great pain and afterward I had what I called hallucinations.... seeing totally weird things that didn't exist. I told a friend of mind - a physician who had nothing to do with the surgery - about them and she said they weren't hallucinations - they were my brains reaction to extreme pain. Wow !!
Whatever they are called or what causes them - it was good to have them end.
