If your Rav says it’s necessary then it’s necessary.
The Gemara says that someone who asks a Shaila about Pikuach Nefesh on Shabbos is a Shofech Damim and the Rav who is asked is Meguneh. I don’t see why this would be so different. There is a life at stake. Why would you waste time asking Shailos or worrying about possible fallout?
