Is Nausea a sign of liver issues

[MMM]

Hi all
I have not posted here for quite some time, I post a lot on bcorg, but always read here and you are all helpful, I am having a difficult time with symptoms lately and not in a good place mentally. I have had ongoing nausea for 5 days not getting better. It feel like a stomach but but not resolving, my SOn was home for 3 days with similar symptoms but went away. I am scared even thought it is very logical to think stomach virus like son. The worry is that it is not going away, and it should be. I am 2 and a half years out from triple positive dx, full chemo, Hercepin, etc. Stage 1/no nodes.
Tha nausea is my only symptom, the only other thing I can say is that I suffer from some neutropenia after tx so may be harder to fight things, but my Docs are never concerned by this.
I would love to know that I should not be thinking liver mets first with just nausea as symptom.
Thanks for any feedback.
