l cannot imagine having to go through this. Being the patient or the caregiver. I guess you find yourself in which ever position and have to make the best of it. Our daughter had cancer and had to have a port put in her chest to receive chemo. I remember that all to well. It beat having to be stuck with a needle every single time she got a treatment. I wonder if your significant other can take a book or iPad or something to occupy his mind during that 3.5 hours?Hugs to the both of you.
