When a person feels pain, their blood pressure usually goes up. Studies show that people exposed to painful things have increased nerve and muscle activity. These same changes raise blood pressure in the short term.

The relationship between blood pressure and how you feel pain is complicated. People who have high blood pressure seem to be less sensitive to pain. When pain lasts for months or years, it is called chronic pain. Something different seems to happen with chronic pain. It may actually cause high blood pressure. Having chronic pain may also cause a vicious cycle and make you more likely to feel pain. Some doctors think that having high blood pressure makes you more likely to have long-lasting pain. Experts still aren’t sure.
