My husband is 87 years old, painfully thin, has dementia, hallucinates, barely eats, too weak to get out of bed. Last night he peed blood when he was urinating and he would moan every couple of minutes like he was in pain all night. Could that be a kidney stone, which he has never had or something else?
Once, at a family event my mother pulled me aside and said "look at this? Is this normal?" She had container with what apppeared to be pure blood. She said "I've been peeing like this for days."
Good grief, I couldn't get her to the ER fast enough. It was a ruptured blood vessel in her bladder that wouldn't stop bleeding...so fairly easily dealt with but it could have been something very serious.
Mother didn't indicate it was particularly painful--or I think she would have said something earlier.
