Are these sentences native ?
Here are some sentences:

1. I have a runny nose.
2. I have a running nose.
3. My nose is running.
4. My nose is runny.

Could you please tell me which one is correct and native, thank you so much.

I remembered that probably it is not native to say "I have a running nose " ,but I do see " running noses" in a picture book:

Wet
Dark clouds,
Rain again,
Rivers on the
Misted pane.
Wet umbrellas
In the street
Running noses,
Damp feet.

Answer

'I have a runny nose'  is speaking generally because it runs sometimes (when you have a cold)
'my nose is running' means right now = I need a tissue

I wouldn't say it the other ways.

Answer

"I have a runny nose" sounds more natural.
