Women and Pain

New research suggests that women feel pain more intensely than men.

When a woman falls ill, her pain may be more intense than a man’s, a new study suggests.

Across a number of different diseases, including diabetes, arthritis and certain respiratory infections, women in the study reported feeling more pain than men, the researchers said.

The study is one of the largest to examine sex differences in human pain perception. The results are in line with earlier findings, and reveal that sex differences in pain sensitivity may be present in many more diseases than previously thought.

Because pain is subjective, the researchers can’t know for sure whether women, in fact, experience more pain than men. A number of factors, including a person’s mood and whether they take pain medication, likely influence how much pain they say they’re in.

In all, the researchers assessed sex differences in reported pain for more than 250 diseases and conditions.

For almost every diagnosis, women reported higher average pain scores than men. Women’s scores were, on average, 20 percent higher than men’s scores, according to the study.

Women with lower back pain, and knee and leg strain consistently reported higher scores than men. Women also reported feeling more pain in the neck (for conditions such as torticollis, in which the neck muscles twist or spasm) and sinuses (during sinus infections) than did men, a result not found by previous research.

It could be that women assign different numbers to the level of pain they perceive compared with men, said Roger B. Fillingim, a pain researcher at the University of Florida College of Dentistry, who was not involved with the new study.

But the study was large, and the findings are backed up by previous work, Fillingim said.

“I think the most [simple] explanation is that women are indeed experiencing higher levels of pain than men,” Fillingim said.

The reason for this is not known, Fillingim said. Past research suggests a number of factors contribute to perceptions of pain level, including hormones, genetics and psychological factors, which may vary between men and women, Fillingim said. It’s also possible the pain systems work differently in men and women, or women experience more severe forms of disease than men, he said.
