Yes, the blood really is unsettling! I had to stop any saline as well.
And though this has been happening in episodes over past few years, I’m new to the diagnosis. In fact in waiting room for CT scan right now after a ton of blood work. I guess it’s just part of what we need to do.

In past my primary care doctor assumed it was pneumonia. And I’d get well after 2 weeks of strong antibiotics and then a lot of rest for another month or 2.
