Bizarre question, but how's your poo?

Is it a normal colour? I had this a good few years ago, like about 20 years ago and mine turned out to be liver inflammation caused by antibiotics I was on at the time.

Liver problems, if they're causing urine issues, can cause bowel issues too. If your poo is a very light colour (white-ish/yellow/mustard) and floating with or without being accompanied by pale stools, it may be something to do with your liver.

All that said, covid is a weird thing. It can cause all strange and bizarre symptoms so it may just be the virus itself.

Or it could be something very simple as being dehydrated. That too can cause dark and orangey urine. Try to drink more water and see how it goes.
