Hello, i have been feeling faint, dizzy very weak, out of breath, confused, and tired even if i walk one flight of stairs, what should i do?

If this is an acute: ...presentation, then proceed at once to the ER now please.

Go see doctor.: Your symptoms generally suggest an issue with circulation, which could be related to the heart, lungs, peripheral vasculature or the blood. Could be anemia? Low blood pressure? Dehydration? Heat valve issue? In other words, too many possibilities. You really need an evaluation by a local doc.
