[|Human|] My 16 month, 26 lbs toddler boy has been hitting/touching the back right side of his head. I found a pea sized lump in that area. Lately he is irritable, has loss of appetite, and will occasionally falls over as though losing his balance. What is happening?
[|AI|]  Hi! Your son got two different problems that are confusing you, but both related to the accidental hitting! You mentioned, Lately he is irritable, has loss of appetite, and will occasionally fall over as though losing his balance.... This indicated injury to brain or the middle ear/temporal lobe possibly an urgent CT scan f the brain is required! And, the pea sized lump at the back of his head is just a small hematoma might be tipped of the iceberg phenomenon. Therefore, please see a surgeon immediately for management!regards,
