Hello welcome to health care magic I share your concern Dizziness is a matter of concern , you may fall and injure yourself, so be careful while standing up or walking, rather take someone s help. Here, I would like further details like your age, relevant medical history and if you are diabetic or having high BP. when do you get dizzy, is it related to particular position or time. In my opinion you should immediately visit emergency room for checking of blood pressure and physical examination and blood investigation if need be, to establish a diagnosis. please write back to me with these details so that I will be able to tell you more precisely. waiting for your reply Best wishes
