I look to my older brother as a model on how to be a good catholic. He had some big bumps/skin tags on his scalp. It’s easy enough to go to a dermatologist and get them frozen off, but as they are benign, mostly, he didn’t worry about them. Though, over time, they started getting bigger and bigger, so each day, during his prayers, he’d dab his finger in a vial of holy water and dab some on his big bumps. He had been doing this for a couple weeks and one day, went to put water on it and realized there was nothing to put it on as they had all disappeared. There is a slight danger in those skin tag things, if they become malignant, they can dig into your body and start spreading cancer.
Minor, but his faith prevailed and preserved through this.
