Are there any ways to relieve wrist pain at home?

My wrists are aching and hurting because I lifted some heavy things while cleaning and organizing.
Are there any first aid or management methods for wrist pain caused by excessive use?

It's a holiday so it's difficult to go to the hospital, but I'm wondering what would be effective for relieving pain at home.
I'm wondering if it's not just muscle pain, but a ligament injury or something else entirely.

Would a wrist brace be helpful if I had to constantly use my wrist?
