Stop if you feel faint or pain! [duplicate]

Ellipsis that results in one word serving as both subject and object
I am “adjective” and I am “present continuous” in one sentence

I was using some exercise equipment the other day and saw the sign:

Stop if you feel faint or pain

It immediately struck me as wrong, because faint and pain seem to force feel to serve two different verb functions. Is that true?

I think correct alternates would be:

Stop if you feel faint or pained

Stop if you feel faintness or pain

Here's a contrived example that exposes the wrongness I detected from it. Imagine you're reaching into a box to feel the objects inside, and you're told:

Stop if you feel happy or noodles

If that doesn't make you smile, you don't live in my world! :)

"Stop if you feel faint or pain" is an example of syllepsis:

A figure of speech in which one word simultaneously modifies two or more other words such that the modification must be understood differently with respect to each modified word; often causing humorous incongruity.

The syllepsis section of wikipedia's zeugma article includes numerous examples of several forms. Both of your suggested revisions correctly improve upon the original wording.
