Fecal Microbiota Transplantation for Patients With Chronic Widespread Pain

This study aims to explore the effect of Fecal Microbiota Transplantation (FMT) on the clinical symptomatology in Chronic Widespread Pain (CWP), to assess the acceptability, tolerability, and safety of FMT in patients with CWP, as well as explore the effect of FMT on the gut microbiome diversity in CWP. The investigators hypothesize that fecal microbiota transplantation will reduce pain intensity in patients with CWP, is acceptable, safe, and tolerable in patients with CWP, and will achieve change of gut microbiome diversity after FMT treatment.
