am living in Uganda, it have a 12year old son who has had a headache for the last 2 months,I wanted to bring him in in August,what are the likely hospital charges?

There is no way of telling.

Without insurance and without knowing anything else about your son's condition? Astronomical

It all depends on what kind of treatment. State of the art hospital state of the art prices.

No way of telling with so little information. I doubt the hospital themselves could answer that question.
