While I was sleeping around 04:00AM. I felt my ring finger in right hand bitten by something. I felt sharp pain and burning sensation for 5 minutes. After this these effects reduced. I searched every where in the room for the insects or reptiles. But I could not find any insects except a lizard at the corner of the wall touched with me. There is to two cut marks on the tip of fingers at 6mm distances. Please suggest what should I do?
