I had a single mastectomy with auxiliary clearance this morning. I have almost no pain in relation to the mastectomy or aux clearance at all. There is a self administered morphine pump that I can use. I have used it twice so far. I do have stinging where the cannula is in the other arm though and that is annoying as I cannot use that arm. I just marched on the spot for half an hour WTF I was not expecting to that!
For me, the physical healing is easier and is for a shortish time. The mental healing is challenging and I cannot see myself ever accepting this fully. So I think it is really important to consider this during any decision.
What I mean by this is not having the mastectomy could cause a lot of stress and worry about it returning which might have a negative impact on your mental health but then having one has its own emotional impact.
I didn't have a choice about mastectomy and have no idea what I would do in your situation.
Sorry if it sounds as if I am making light of the physical recovery but our mental health is also really important and also that this is a long post.
Pen and paper, two colums, pros and cons and if you have a trusted friend or family member (if you are telling people about this) involve them and list everything you can think of in the appropriate column. Don't know, might help.
Chat with a breast care nurse?
Good luck :)
