Pain can cause temporary high blood pressure, but the pressure decreases after some time, according to Health Central. Unrelieved pain patients are at a greater risk of increased sensitivity to acute pain and high blood pressure, as explained by Pain-Topics Updates.
Presence of chronic pain increases the risk of having hypertension. A study conducted to determine the relationship between pain and high blood pressure showed that chronic low-back pain increased the risk of having high blood pressure by 50 percent, according to Pain-Topics Updates. Chronic pain is a significant contributor to the persistence of high blood pressure. Prolonged use of over-the-counter pain reliever drugs can cause high blood pressure, according to Health Central.
