Hi there I am one week post op today for a WLE, nipple excision and sentinel node removal in left breast. Diagnosed with DCIS and grade 1 but waiting on results of surgery. I have been doing the BCN exercises but struggling with No’s 4 and 6. I appreciate I am 1 week out but today it seemed harder to do them than when I first started. It pulls and is tender and I am the kind of person who has a high pain threshold and likes to see progress LOL! Is this normal and just wondered when it might improve to where I can do the exercises more easily. There’s no redness and no signs of cording that I can see anyway but it’s just so tight and sore when I reach a certain point in those particular exercises. Any advice or support gratefully received! Thank you
