Is your Vet grey-savvy? If so, then consulting with OSU shouldn't be an issue - there are MANY benefits to be had as a result of doing a consult.
If your Vet isn't particularly grey-savvy, then PLEASE take the advice offered free of charge here from those who have been there. GTers are the best - hands down, no questions asked - absolutely unrivaled, in my opinion. Your decisions will have our 100% support, and everyone will be here to hold your hand, cheer you on, provide hugs of support and cry with you.
Welcome to GT, and I am so very sorry that the possibility of this diagnosis brought you here, but you have landed in the right place. Please update when you can.
