Ring them that’s what they’re there for! I went to my nurse 3 times instead if the usual 1 time 7 day check, and spoke to her countless times over the phone and corresponded via email sending pics when I had a reaction to the tape. To be fair the nurses at birmingham have always made me feel comfortable to phone them. If you don’t get the dressing on right it could rub and you could blister. So def phone them. I’d rather be a pest than uncomfortable xx
