Hi @LucyLou55 and welcome to the forums. I hope you are enjoying your holiday despite the foot issue.
Can you tell us what you did to make your feet swollen and bruised? How are your blood sugars?
Forum rules don't allow us to give medical advice but we can describe our own experiences.
Are you able to see a medical practicioner should that prove necessary? ( As a T1 I am always a bit wary about possible foot complications though so far all my injuries have come good.)
