My urine is always darkish yellow now. It used to be clear or almost clear. I've been drinking more water (2-3 liters a day at least) - I'm always thirsty lately as well; I drink constantly but it doesn't help; but it remains yellow. Until a few weeks ago my urine was almost always colorless if I drank half that amount. It's stronger smelling as well. (No, I'm not deliberately smelling it, LOL. But I can't help but notice it.)
I've also been having swollen-feeling knees and lower legs, off and on for a while now. I can't tell if they're actually swollen or it's in my head, though. And the soles of my feet and hands are often itchy. I'd written that off as anxiety, but then I googled. (I know, I know.)
So I'm worrying about kidney problems, especially kidney cancer.
And I've been extremely fatigued for the last week or so. And I do have bad low back pain, but that's more or less normal for me; can't tell if it's anything different. And I have a godawful headache, but my neck was super-painful to touch for a while today, so I'm guessing it's just tension.
