How to Treat an Infected Finger

Finger infection.  Ouch.  I’ve had to deal with them, and I know that not only is an infected finger painful, but it also adversely limits what you can do throughout your day.

What is a typical finger infection?

Nail infections can occur for a variety of reasons.  Bacteria is the problem, and it does not like to get out easily.  Bacteria can get it through cuts or breaks in the skin.  Infections can quickly get into the fingernail through the cuticle and around the nails.

If you do happen to have any breaks or cuts in your skin, you’ll want to cover it and keep it protected from bacteria that is everywhere in the world around us.  You may want to apply a antibacterial ointment (like neosporin) before you put on a band-aid over the wound for good measure.

Salt Water Soak:

Fill up a small bowl of water, dissolve some salt in it, and then soak your finger for 5-10 minutes.  The salt can help to fight the infection.


Iodine does disinfect which kills bacteria.  What you can do is make sure it’s diluted to a safe amount and then soak your finger in it for 5-10 minutes.  You can also put some on before you put a band-aid on.

Be careful with it though, because it can stain clothes.  If you want to get the color off of your skin, you can use rubbing alcohol to get it off easily.

Antibacterial ointment:

You can use antibacterial ointment like Neosporin, then protect it with a band-aid.  Remember to let your finger air out occasionally.  Bacteria likes damp, dark places after all, so it’s good to let it air now and then.

Don’t cross contaminate!

Do not use the same tools, or anything that has gotten into contact with the infected finger, with other fingers,  You do not want to spread the infection to another finger.  Make sure that you wash and disinfect anything that came into contact with the infection.

Get medical attention:

What is recommended here are things that can potentially help, but you seriously should get professional help to get rid the infection.
