I had the same as you are going to have. I didn't have much pain and an ice pack was handy. The one under the armpit will give you more discomfort than the incision on your breast. Wear your post op bra in bed as it will give you the support you need and yes don't forget to do your exercises cos it will give you back your mobility in that area...lots of shoulder rolls! One interesting point...beware of getting an awful case of constipation a few days after surgery. I unfortunately copped that last week after my second surgery. It's to do with the painkillers they give you, they can bind you up. Coloxyl with senna is good. You can get it over the counter from the chemist. My GP said to take it the day after surgery and keep taking it for a few days till things seem normal. Good luck with your surgery Xx Cath Oh and cos you can't really use deodorant where they took out the lymph node use cornflour when you need it...i found it worked at keeping me dry.
