The boy, who belonged to Sukraguda village, was admitted to the district headquarters hospital here last night in a serious condition, the doctor who was treating the boy said.
The boy had probably been branded with hot iron about five days ago and the family members brought him to the hospital when his condition turned critical, he said.
As the child was suffering from stomach ache and fever, his grand-father applied the crude method in an attempt to cure him, doctors said.
No police complaint has so far been lodged regarding the incident, police said.
