I had to have mine on for 11 days! But if you are reacting or if you think there is something wrong with your boobs, you should ask to take it off. I thought there was something wrong and I called the emergnecy number and the nurse on the other end of the phone told me off for calling without even asking what was wrong. When I finally got tape off, it turns out I have excess swelling which needs antibiotics, anti inflamatories and possibly draining – it would have been better if they’d caught it earlier. Trust your instincts! xx
