Engorgement feeling 8 days post op breast reduction.

Ok so the all over rock hard engorgement feeling went away. Whats left is only felt on the outsides of my breast. It's not completely hard all over as it was earlier. I applied a heat pack for a few minutes today and then have been applying ice packs. Some of the engorgement has gone done but there is still a few lumps in the area where I had the drain. When I massage the area it feels like little knots which are a little sore. No fever, no warmth or redness at the site either.
