I think I have developed some kind infection in the fingernail of my left ring finger. The nail itself is not painful or discolored, but the skin along only the left side of the nail is very sore and tender and is red and slightly swollen, especially out closest to the tip of the finger, at the corner of the nail. Neither the right side of the finger nor any other part of the finger is affected whatsoever and the symptoms are not present in any others places on my fingers and hands. Is anybody in here familiar with these types of symptoms? Is this some kind of common nail infection? And most importantly are there any really effective home treatments or remedies I can use to clear up the infection and help avoid a recurrence?
