Thank you. I am so sorry to hear that your dad is not doing well. My father was dignosed in Feb of this year, so far he is doing well. But I know the day will come that he will not be doing so well, and I dread it. We are all fighting for him and with him to beat this and hold that day off as long as we can.
I will be sure to tell dad about the patch, and I am sure he will want to ask his dr about it. Best wishes
