Good day, we have a neurologist who ordered Diacarb and Aspartam for us after an ultrasound in the fifth month of pregnancy. The fluid seems to be present in the head, intracranial pressure. However, we don't have any symptoms. Our child eats, sleeps, plays, crawls, sits. He sleeps well at night, but he wakes up three times a day for about an hour and a half. In general, she started giving him medication, he began vomiting profusely, crying, couldn't put him down for three days, and stopped. I think it will normalize by the year. Has anyone encountered this? How were they treated? What did they give?
