Hello doctor, I am sibi. Now I am 18. 3 years before a dog (3 months old) scratchs me with teeth slightly in my finger on the outer skin not deeply. I am sure it is outer skin. After that I cleaned it well with lots of water. I can't seek any medical advice after that. Can it cause any problem in my future. In this 3 years and now I am fine without any disease or any other symptoms including fever, flu,.
