I'm glad there's more research on this, but that doesn't help those of us who have struggled (sometimes for decades) with this, and who, despite visits to many doctors, have never been able to find a solution except symptom management with drugs that seem incredibly harmful if used long-term.<p>Could this be psychosomatic? Has anyone here found that therapy ended up resolving this issue? That's about the only hope I have left for resolving this.
