I know there is no cure for the common cold, but if y'all have any home remedies that have worked for you, let me know

You can use a cotton swab to put something like a tiger balm under your nose to relieve a runny nose.

What I'll sometimes also do is take an antihistamine. It'll dry out your nose as well. It supresses the immuno response so it's probably not the best idea. But it can help with your sleep if you take one before bed.
