Brief summary (from the registry)
Chronic, unexplained pain symptoms are very common in all layers of the population, but it is largely unknown what causes them. This study examines the hypothesis that patients with these pain symptoms process pain abnormally in their brain. TO this aim, we compare patients and healthy people: they receive mild pain at their painful body region and at another location. Concurrently, we measure brain activity with brain scans (functional MRI scans). With our study results, we want to increase understanding of what causes chronic, unexplained pain symptoms, in order to find better methods of diagnosing and treating them.
