SO sorry to see you join our 'exclusive little club' @Olivegreen ..... it is really good when you find 'your tribe' as it is important to feel confident/comfortable in the info that you are receiving xx. Pretty well everyone here has 'been there', 'done that' .... so hopefully will be able to answer any query you have, with honest answers.
Having said that ...... I had a 'sentinel node test' the day before my surgery & I don't recall being told NOT to shower (but my memory is notoriously BAD!) & I am not familiar with that particular procedure ..... it may be worth checking with your Surgeon's Breast Care Nurse (or McGrath Nurse, if you've been assigned one .. ) just in case. I'd be surprised if you can't do an 'APC' wipe down at the very least ... (arm pit and crutch) .....
Being a sook is absolutely FINE! I bawled as I said goodbye to my husband, brother & SIL on the day I was admitted ..... but then I was also FINE once I got upstairs to my room!!! I was SO relieved the next day, following the surgery, too ....
Feel free to jump on this thread & see 'other bits' on the forum, that may help you prepare for the hospital & even give light relief over the next few weeks ..... even funny bits, as we all need a laugh!
