Sorry that you are 'joining' us under such circumstances. Those early days of waiting are hard. An emotional rollercoaster. I personally found one moment I was coping like a trooper, the next I would burst into tears. But that's ok. The surgery will give you a much clearer idea of what you are dealing with and the treatment that will follow. Until then it is just a waiting game. Like you, I read everything I could in the meantime, trying to filter out all the garbage. And I told all of my family and friends as I knew I would need their help and support.
Not everyone ends up with a drain in their armpit after removal of the sentinel nodes. I had 8 nodes removed and no drain. And they were all clear which was good news.
We are all here if you need to vent or ask questions. So many ladies here with so many different experiences, there will always be someone who can help out. I won't say 'stay strong' because, you know, some days it's ok not to be.
Best of luck on the 14th
