Hi Robyn
I've report to the Onco when it wasn't that bad, they arranged a scan (just in case blood clog) for me, but it all looks fine.
I was sitting in the car since 7:00 in the morning until around 3:00, and then supermarket something, and then dinner out, and sit from 6:00 to 10:30pm, I wonder that's why it caused.
I was also thinking about the kidney which wee wee not enough, I'll try to observe one more day today, drink plenty of pure water, and take a little walk, staying home, to see how it goes.
THanks Robyn
