Because high blood pressure (when it's severe enough) can cause untold problems for all the major organs of the body, you don't want to miss the signs and have your high blood pressure go undiagnosed for any lengthy period of time. Complications can include cardiac problems, liver and kidney disease, as well as potential vision problems and stroke.

Physical high blood pressure signs include:

Headache

Ataxia (Difficulty with walking)

Convulsions

Blurred Vision

Tremors

Giddiness

Some of these signs can easily be mistaken for other problems. In addition, high blood pressure can be a symptom of another problem. So it's always wise to have your blood pressure checked on a regular basis, even when you suspect something else may be going on inside your body.

Some of the high blood pressure signs mentioned above can also be related to diabetes, especially for those diabetics suffering a hypoglycemic attack. Unfortunately, these signs also mimic the signs of someone who is very drunk. There have been occasions when someone suffering from the side effects of high blood pressure has not been treated correctly because it was assumed they were under the influence of alcohol.

If there's cardiac damage due to elevated blood pressure, then the patient may complain of lethargy and tiredness, even after minor exertion. They may become very breathless and clammy. This would be due to damage sustained to their heart, which would need to be investigated and treated as a matter of urgency.

Other physical signs of high blood pressure may relate to excretory organs such as the kidneys. Patients may complain of pain when urinating, or may complain of the frequent need to urinate. There may also be signs of dehydration and dullness of the skin due to a loss of electrolytes in the body.

Other physical signs of high blood pressure may be lesions in the ocular region. If the retina or blood vessels supplying eyes are affected, there may be a disturbance in the patient's vision. If left untreated, there's a real possibility the patient's eyesight could be in danger.

Finally, other physical signs of high blood pressure may also include increasingly lethargy, with a reluctance to move or do anything. This may also be accompanied by signs of clinical depression.
