Can your finger swell up after a sting?

Yes, a finger can swell up after a sting. When a person is stung by an insect, such as a bee or a wasp, the venom from the insect can cause inflammation and swelling in the affected area. This is a normal reaction to the sting and is usually not a cause for concern. However, in some cases, the swelling can be severe and may require medical attention.
