Sir/mam I am suffering from initial stages of fistula since about 2 -3 months. Could be this because of junk food intake? Please answer it and suggest ways to overcome it. MY CONDITION IS--i am having a small lump outside near the anus and I never suffer bleeding or any other type of liquid flow from lump. But in starting period of its development I suffer from a huge itching and pain in anal area. Now I am completely free from itching and pain by taking medicines but small lump is there inside the skin. Sir/mam give me proper advice my age is 19 (male).
