I too have a colostomy from cancer and have had a hysterectomy while under going the cancer removal. I will have to research about the stints and how ones body does when having the kidney and thyroid removed.
But please don't push yourself to hard. It can take a long and steady road for our bodies to recover. Your body knows best on when to shut down, listen to it. Hope to get to chat with you in real time in the general chat sometime.
This may not be helpful to you in a practical way but it was useful for me to be able to share it with someone in this way.
Best wishes Bill
