a runny/running nose

[joham]

When we have a cold, we can have a runny/running nose.

Can both words be used, or is only runny correct?

Thank you in advance.

Within the context you have supplied, only "runny" works.

Thank you very much, JohanParis. Then might I ask when we can use 'a running nose'? Thank you again.

Here's a previous UE thread that will answer your question with several examples.
