Hello sir, My name is Gangadhar and I am from India. An outside dog bit me on my leg. Because my trouser is thick, I didn't find any bit mark on my leg. I found some reddish skin like scratching on my foot and it was vanished after some time. I found no wound and I am not feeling any pain right now. Is it okay or should I consult doctor. If doctor asks me to show wound, I can't. Because nothing is visible.
