14 Common Signs of a Sprained Thumb

2. Swelling is a common sign of a sprained thumb. 

The swelling of a sprained thumb will cause you to be unable to grasp objects. Compression will reduce swelling and pain in the thumb. When you compress it, you can place a splint over it as well. That way the splint will help keep it in place while the compress will reduce pain and swelling. 

When you compress your thumb, make sure to not wrap the elastic bandage around too tightly. It could cause more swelling and pain. Once the swelling goes down, take off the bandage. You may want to take the bandage off at night to allow your thumb to breathe. 

A lot of the time while you rest, the swelling could go down on its own. In the morning, wrap it back up if the swelling is still there. Be gentle with your thumb while wrapping it as well.
