What are symptoms of hypertension?

None. Usually none; that's why it's a silent killer. If it is very severe it sometimes causes a headache, vision and neurological changes.
Wide range. Usually there are no symptoms. Every person's body reacts to elevated blood pressure differently. You can feel generalized weakness and fatigue, dizziness or vague fuzzy-headedness, headache, blurry vision, and flushing. People commonly feel vague chest pressure or discomfort as well, which most often does not indicate any heart damage or dysfunction.
Usually none, but... "silent killer" is a very fitting description, and this is why it is so important to treat high blood pressure even in the absence of symptoms. Severely high blood pressure (example 180/120) combined with headache, chest pain, or vision change is a medical emergency and deserves a call to 911 to avoid permanent damage or even death.
