When should I see a doctor for a cut?

I have a cut on my arm. How do I know if I need to see a doctor?

It depends on several factors. If the cut is deep, won't stop bleeding, or shows signs of infection, you should see a doctor.

What if the cut is just a small scrape?

For small scrapes, you can usually treat them at home. Clean the area, apply an antibiotic ointment, and cover it.

How do I know if it's infected?

Signs of infection include increased redness, swelling, warmth, pus, or if you develop a fever. If you notice these, consult a doctor.

Should I get a tetanus shot for my cut?

If the cut is deep or caused by a dirty object, and your last tetanus shot was more than 5 years ago, you should get a booster.
