If you have an infected finger, it is important to seek medical attention as soon as possible to avoid serious complications. However, for a minor infection of the finger, you can try the following home remedies:

• Soak the finger in a mixture of pre-boiled warm water with antibacterial soap for 15 minutes, two to four times a day.
• Soak the finger in water with Epsom salt to soothe the area and provide pain relief.
• Apply apple cider vinegar because it has antibacterial and antifungal properties.
• Apply an antiseptic solution of warm water.

If you do not find any improvement in one to two days, you should see a doctor at once. The mainstay of treatment for finger infections is antibiotics and proper wound care. The proper wound care varies for each of the different infections, and this can range from a simple incision and drainage of the wound to an extensive surgical exploration of the wound to remove as much infected material as possible.
