I am 20 years old and I'm suddenly facing this problem, where I get so dizzy and my heart beats increase and I just cannot stand still. Its been 3 days now and even after taking medicines, I see no change. Its been 3 days now and Its affecting my eyes too, my vision has become blur. The name of the medicine that the doctor prescribed are -Be Still 16 and Stugeron. Is this anxiety attack. I haven't been able to stand since 3 days and sudden heart rate increase and constant blackouts and blur vision. I've always had this problem, where I would back out sometimes when I suddenly got off bed or a chair but it would happen sometimes but pst 3 days I'm facing this 24/7. I can barely do anything, I've become extremely slow.
