Uh oh...

I'm basically cured from my lung problems, phlegm is much less recurrent and I don't need to blow my nose as often.

But the pain is still there, but at a much lower area in my body. It's way too below from the lungs that it just can't be considered borne from within the lungs, as a lung infection.
My prediction is that now the problem is with my left kidney.

However, my predictions are much less plausible than the observations of a professional. I shall get this problem checked as soon as possible. This is driving me crazy!!
