Weaning and tender boob question

I am not sure where to ask this question but I know you all have a lot of experience. so...
Evan and I have slowed down gradualy to one nursing a day. Now it has been a week since we have nursed and I feel very tender. also feel some hard sore lumps. Thenurse on the phone at my OBGYN said no to worry unless I am running a fever. She also said I should bind myself to encourage drying up. She said it was not neccesary but it would help with the pain. I would appreciate any advice you have in this regard. Thank you so much,
