Hi, I have had an infection in my finger for About 8 days. I believe that it is paronychia. A few days ago I noticed severe pain in my left underarm, and the following day I began to have flu like symptoms. I have full body aches, fever, and the pain with the finger, as well as swelling. Not really sure if this is something that I can treat at home , or if I need to seek my doctor. Thank you so much .
