Another, better update from me- so after thinking for a few days and being treated for kidney infection, the urologist decided that it couldn't be (symptoms not adding up, no fever, etc..), and I was sent to another cat scan. This time with the contrast. It revealed an obstruction and I had surgery this morning to correct it, and he was able to put a stent, to drain, finally, my poor, enlarged and completely non-functioning left kidney. The relief was constant. I am now on only oral pain medications, and can go home tomorrow and start enjoying baby moon!
What a ride this has been. But somehow, it brought our entire family closer together, and gave friends and neighbors the opportunity to show how supportive and loving they are. Wouldn't have been possible without them.
Thank you for all of your warm words and encouragement.
