My surgeon said 24 hours post op I could shower. I had to be careful raising my arm, but as long as I took it slow and was careful I was ok. I felt so much better after showering. I had steri strips (white tape) covering my stitches and was told to keep them on till they fell off on their own- I had to peel them off after my 10 day post op visit, they stayed on that good! The one issue I had after the axillary node dissection was I heard and felt "swishing" when I moved. I wasn't sure if it needed to be drained, so I made an appointment and was reassured that it was normal and it did go away on its own. Best of luck with your recovery!
