Hi @Leilani - SO Sorry that you've 'joined the club' - but you are in the best spot for the best advice, here on BCNA! ;) I hope everything is going well for you.
I didn't like the feel of the bra after my surgery, so only wore it for a couple of days when I got home - tho it sort of protected my surgery area (my whole nipple was isolated & all surgery done under it & then sewn back on.) And I wasn't really used to it either, as I'd never worn one prior to surgery for 40 years! Yeah, I'm an old Hippy! Even tho it was a soft 'sports bra' type - it sort of felt too tight for me (and I tried different sizes too.)
The under arm numbness can hang around for quite a while .... everyone is different. As @iserbrown said - it feels so weird when putting deodorant on as you are not sure if you missed! You don't even feel the 'coolness' of it, let alone the path you took with it! ;) Use the mirror :) (I found that I actually needed MORE deodorant post surgery too, as I seemed to develop a really STRONG BO problem in that armpit!! (Maybe it was just sweating more due to the 'trauma' of the surgery?) It has settled down now, tho I have also changed brand of deodorants!)
How wonderful that your daughter has been so supportive of you. That is terrific. Re your niece's BD ..... yep, see how you feel - and that is with EVERYTHING you do from her on .... Don't be afraid of trying to get back to doing what you love 'as you feel up to it'. It could well be the best therapy for you!
After my surgery, I almost felt like wearing an arm sling once I was getting 'out & about again' - so that it restricted me from doing too much with it until I was able (reaching for high things, picking things up etc.) It also advises 'others' (like in supermarkets etc) that you have an injury & don't want to be jostled?
All the best for your recovery & treatment xx
