I had a wig throwing tantrum during my 4th chemo. Literally ripped it off my head, threw it on the floor and stamped on it. I was furious with my oncologist who had failed to inform me that I had to have a particular shot after chemo after I'd asked him, very clearly, the day before if he'd written it up.
Oh how I hated that man--I've dealt with some absolute flogs in my time, but he took the cake. So, wig stomping, recriminatory phone calls, sedation, the whole 9 yards. They had to get one of the paramedics up to cannulate me--I was so mad that all my blood had moved to my head and no one else could find a vein...
The oncology unit manager still treats me with kid gloves 12 years later--though she has admitted in private that she wishes she had recorded the conversation for further reference when he did similar things to other patients.
