So an ambulance took me to the emergency room. After a CT scan I was diagnosed with hydronephrosis - fluid collecting in the kidney because a tumor was blocking the drainage. I was in surgery by morning to have a stent placed and have just returned home.
The pathology report is due by Friday and then a treatment plan will be completed. As things look now, because the tumor is small and localized but in an odd place, it looks like weekly radiation will zap it - but that idea might change if the pathology report has new information to be considered. At any rate, I don't expect this next chapter to be the ordeal of the past year, just a blip.
It better be because I plan to start school on Monday night.
