Asymptomatic

• For many people suffering from renal hypertension, few, if any, symptoms actually present themselves. It isn't until the blood pressure hits a severely high level that signs begin to manifest. However, you may begin to suffer from more frequent headaches, with most not realizing what the cause of the headache really is.
  
  

Pain

• In some cases of renal hypertension, especially when renovascular blood pressure is high, you may experience pain. This pain is usually isolated within the chest and is generally heavy or sharp in nature. It can also be accompanied by an irregular, uneven or pounding heartbeat.
  
  

Bleeding

• With renal hypertension, it is possible to experience some bleeding. In this situation, you could begin to suffer from more frequent nosebleeds or even notice actual blood in your urine. When blood is present in the urine, it can change the appearance of this fluid, resulting in a pink, red or dark brown hue.
  
  

Cognitive Changes

• Renal hypertension has also been known to alter a person's cognitive nature, prompting periodic episodes of mental confusion. Depending on the person, this symptom can reveal itself in a number of different ways, causing you to forget things or retain recent events, as well as lose your orientation of time or location. For others, this symptom may simply manifest as an unexplained feeling of tiredness or exhaustion.
  
  

Auditory Changes

• Sometimes, renal hypertension can trigger an auditory change, prompting you to suffer from a buzzing, whirring or ringing in the ears. And as with almost any symptom, this noise can be persistent or recurring.
  
  

Vision Changes

• For some people, renal hypertension can cause a change in visual perception, eliciting double or blurry vision.
