I pulled the cuticle from my fingernail about two days ago, and now it's be!

Yes, it can get worse. Because finger infections have the potential to become severe, home care is limited. A very minor paronychia may be managed at home if you have no other complicating medical illness, such as diabetes. All of the other infections require urgent evaluation and treatment by a doctor. There are some things you can do if you cannot get there immediately.

Pour some boiling water into a shallow cup. Measure a 1/3 cup of Epsom salt and pour into your cup of a boiling water. Stir until Epsom salt dissolves. Let the cup of water cool down until you can stick your infected finger into it at the highest temperature you can stand. Let the infected finger soak as long as possible.

At some point after the finger has soaked for a good long while you should see puss from the infected finger start to seep out. You may want to help squeeze some of the puss out of the finger after it's soaked in the Epsom salt water. The water helps soften and prune the finger making it easier to force the puss out.

You may need to do this proceedure several times to remove all the puss. Between those times use "Neosporin" and wrap your infected finger up with a Band Aid.

See a doctor if it does not seem to be improving or if you see red streaks coming from the site of the infection..
