Why would your thumb swell up and ache 2 days after taking out a splinter or metal burr?

Answer 1

When there is a puncture wound, even when the splinter or burr is removed, germs may be left behind by the object, dead skin, or outside air. Any of these can result in an infection, which can be trapped beneath the closed entrance of the wound. The body's repair and immune processes can often cause swelling, inflammation, and subdermal pain for several days after the injury.

Topical antibiotic ointments can prevent and relieve some infections. If the wound does not improve within a few days, or the affected area becomes larger or more painful, consult a medical professional to avoid potentially serious complications.

*For animal bites or deep wounds, physicians typically administer a tetanus shot to avoid at least that one common infection. Individuals who have received a tetanus booster are considered generally protected for about 10 years.

Answer 2

It can be one of two things: it can be a normal reaction as the tissue is damaged or you have an infection starting.
