does high blood pressure have any noticeable sensations?

  I have periodically had high normal blood pressure (~138/87) and was
  wondering if there are any symtpoms of an episode of high blood pressure
  that one can feel within the body.  
  Thanks for your help!

Dear Brian,
Q: Are there any symtpoms of an episode of high blood pressure that one can feel within the body?
A: Not with typical elevated BP.  Extremely high blood pressure may lead to headaches, visual changes and chest pain.  If you should develop any of these symptoms you should go to your local ER for evaluation.

Below is some additional information on high blood pressure.
High blood pressure, or hypertension , is defined in an adult as a blood pressure
greater than or equal to 140 mm Hg systolic pressure or greater than or equal to
90 mm Hg diastolic pressure. Blood pressure is measured in millimeters of
mercury (mm Hg). High blood pressure directly increases the risk of
coronary heart disease (which leads to heart attack) and stroke (or brain
attack), especially along with other risk factors.
High blood pressure can occur in children or adults, but is particularly prevalent in
blacks, middle-aged and elderly people, obese people, heavy drinkers and women who are taking oral
contraceptives. Individuals with diabetes mellitus gout or kidney disease have a higher frequency of
hypertension.
How do salt and sodium affect high blood pressure?
Most Americans consume far more salt (sodium) than their bodies need. Heavy sodium consumption increases blood pressure in some people, leading to high blood pressure. People who are diagnosed with high blood pressure are often placed on restricted-sodium diets.
Reducing sodium (or salt) consumption may help lower blood pressure in some people. Your doctor may
recommend a sodium (salt) restricted diet. This will mean you'll have to avoid salty foods and cut down on the amount of salt you use in cooking and at the table.
How does being overweight affect high blood pressure?
Studies have shown that body weight, changes in body weight over time, and skinfold thickness are related to changes in blood pressure levels. These factors have been linked to the subsequent rise and development of high blood pressure. People who are overweight are more likely to have high-normal to mild high blood
pressure.
Physical inactivity is a risk factor for heart disease. In addition, a sedentary or inactive lifestyle tends to
contribute to obesity, a risk factor for both high blood pressure and heart disease. Regular exercise helps
control weight and lower blood pressure. Don't be afraid to be active
