Recovery is obviously different for everyone but this is what I found helpful.
I think it is very helpful to know that sharp pains are sudden and not expected when the nerves come back. I found that there really wasn't much I could do but massage, massage, massage.
I also took advantage of any valium they could provide as my breast muscles would "freeze" up or "charlie horse" on me often, one side in particular. I still at week 6 have issues with that on one side but just try not to use my right arm much when that happens. Even just moving a dish or opening a door uses those muscles.
Take complete advantage of the pain meds and do exactly what your Dr. says!!
Remember you will feel like it's no big deal but it is major surgery so even if you feel pretty normal you will tire easy and using just your arms will be using those muscles and they need time to rest.
I had a great bra too, UnderArmor zip up front, it is soooo helpful!
Remember that the way you look from week one, two, three, four, five, and six are all different and so be patient! I am amazed today even more than last week at how great I look!
Man I love my Dr.!
