Suggest Treatment For Pus Filled Toenail

Hello Sirs I have been suffering from pus in my Toe since last 2 years again & again at 6 months intervals. I used to pull out the nail of Toe once before six months but again the nail is being large and touches the muschles of Toe and gives as much pains but till now I did not find any permanant solution. Will be thankful if you can advise to get relief for the life. Thanks!
