My father had an accident a week ago, got hit in forehead,and right on that day we had the CT scan done. My father started complaining about the severe headache. Neurologist pointed out subdural bleeding that was very minor, and he said that it would get well by itself in few days. But the pain is not going away, rather it is increasing, which led me to think that blood is continuously flowing out. In the meantime, father was taking IBuprofen and Flagyl together, which I think makes blood thinner. I adviced another CT scan to be done and so it was done, but this one does not have traces of blood as clear as they were in the previous scan. Is it that bleeding has stopped and everything is fine or Is it that blood-thinner medicines caused the removal of blood clot? Headache is still severe.
