Help - Any tips for Surgery?

I agree with the others that you've been thro' the worst of it already with the 7 rounds of chemo.  I haven't personally had chemo, because my type of breast cancer was assessed as not benefitting from it.  But I had already looked into what is involved & had heard the experience of others,  However,  a few months before I was diagnosed I had open heart surgery to replace a congenitally malformed aortic heart valve.  Then I later had a lumpectomy.... which was followed,  a few weeks later,  by a mastectomy to avoid radiation therapy which would've affected my new biotissue heart valve underneath.  And, honestly, none of that surgery was too bad at all.  So many things were the same.  Like pain relief came from keeping up doses of 2 panadol every 6 hours.  The trick the medical staff told me was to keep any pain covered & not wait for pain to push thro'.  Seems that helps healing better, too.  Also I used the same QV Soapless wash & white cotton facewashers to keep the wound area clean.   The nurses were brilliant with their help in all cases.  There was basic physio afterwards , too.  I can honestly say I was never in pain after any of those 3 procedures .... only hurt a bit for a while if I moved my arms sideways (heart surgery) or upwards (breast surgery).  Not that I want any of them.... but it'd strike no fear into my heart if those surgeries had to be done again.     So chemo, for me,  would be an entirely different challenge from surgery & you've been thro' that.  Maybe, as someone else said, you're feeling a little fragile after that treatment so far.   Warmest best wishes coming your way.
