Why pain affects men and women differently

Sexually dimorphic pain signaling mechanisms

NIH-funded research Duke University · NIH-11142561

What this research studies

If you take part, researchers will work with adults who have two or more chronic pain problems and collect clinical, psychological, and biological information from you. They will use those measures to group patients into distinct clusters and compare those clusters between biological females and males. The team will also use laboratory experiments to follow up on biological signals tied to those patient groups. Their goal is to find the underlying mechanisms that explain sex-linked differences in overlapping chronic pain conditions.

Who could benefit from this research

Good fit: Adults (21+) who have two or more chronic pain conditions such as fibromyalgia, temporomandibular disorders, or migraine are the most likely participants.

Not a fit: People without chronic pain, children, or those unwilling to provide clinical information or biological samples are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this could point to sex-tailored ways to diagnose and treat people with multiple chronic pain conditions.

How similar studies have performed: Previous research has identified patient clusters and sex differences in chronic pain, but applying those findings to guide new treatments remains limited.
