Nick Cannon Is Still Worried About His Kidneys

Oh no!
We were sure everything had passed by the way he was talking about recovering, but according to a new tweet, Nick Cannon is still worried about his kidneys:

I live my life walking in faith and only believe the report of the Lord, so at times I may down play my kidney condition, but it is serious.

That’s no good, and troubling to hear.
We wonder what’s actually wrong — we know that whatever it is is resulting in kidney failure, but there has to be a cause for it, right? Is he in need of a transplant? How worried should WE be??
Especially after he said he was feeling “100% better.”
Keep us updated, Nick! We just want you to be healthy again!
