Hi Vikkie,
Yes, I have the same lymphadema in my left breast. I have had it since they removed the drains almost a year ago. I have been to physical therapy two different times but it doesn't go away. I have to do massage on it one or twice a day. My oncologist said it probably wouldn't go away. Its not painful or noticible so I'm just living with it. I think it would be worse if it was my arm. The OT said it was because they took all of the lymph nodes, there is no place for the fluid to drain to. When I massage, I try to direct the fluid into my abdomen or mediastienal area but I don't think that really does anything. I usually don't know that its there. My onc said the problem is if you just let the fluid sit, it might become infected. I said maybe it would have been better to have had a mastectomy but she said that the same thing can actually happen with a mastectomy. I can live with this. Hope it helps to know that the same thing has happened to someone else.
Take care,
Nita
