Always capitalize I and put space after a) and b)

Re: How long after-can it be used in the following way?

a)Michael ask, How long after he not showing up should i call him?

How long after he doesn't show up should I call him? OR
How long after his not showing up should I call him?

Jane answered, one or two hours after he don't show up, you should call
him.

You should call him one or two hours after he doesn't show up.

b) How long after if my pain don't go should i see the doctor?

In this context, we don't really use "How long after" with a negative (pain doesn't go).

If the pain doesn't go away, how long should I leave it before I go to the doctor?

See above.

This is a duplicate thread. I just answered the exact same question on another thread.

:up: 'How long should I leave it/wait/put up with it before...' is a very useful expression. ;-)

It's always rewarding to know we spend our time well. I will merge the threads.
EDIT: Oops. I merged the posts instead of the threads, but I got there eventually.
