Hi , Rach I did experience the same after my sentinel biopsy on 7/7/11 it felt like cords running down from under the breast to the hip . My surgeon told me it will go away after 3 weeks and it is caused by distruption to the lymph fluid, sometimes it is called cording if you do a google search you'll find some info regarding cording in the arm post lymph nodes removal but it happens after sentinell node biopsy as well. What helped me was massaging the area with vit e cream after shower and just massaging the area in the shower under the warm water ,first time I did it it felt as if something popped and it felt better after that. Hope this helps but if concern just see your surgeon. Try and slow down and do not strain the side where you had your sentinel node biopsy as it could lead to lymphodema as I was told by my breast care nurse. Good luck and speedy recovery , Monica
