Hello Doctor, Past 8 months running after anexity which makes me to feel negative thoughts alone. So I took all scan and xray and even cardio too all came negative. Now brain is paining and feeling like I will fall down and die. When I checked my BP it is normal. Should I take brain scan for this. And also saw doctor who prescribed oral drop 'Passifiya' will it help to reduce my anexity? Please advice. I really don't understand at all, all of a sudden why I am turned like this and fear of death. I never had this feeling. But when I checked my endoscopy they told I have acidity. Will this acidity makes all these thinking.
