Sir, I've been looking at the black side for a while, and I'm worried.

I think you're experiencing melena, and the symptoms and the history indicate that you're suspecting ulceric colitis.
Doctor, your nails break, your throat hurts, your back hurts, and why?
The symptoms seem to indicate that you're suffering from genker's diverticulitis, a condition that causes trouble and throat pain in the back of your neck, but the backache isn't the symptom of this disease.
