question: Hello, I have had upper buttock pain around the sacroiliac joint for 2 years - right side. I also have pain in my right calf and the outer side of my right foot. I have seen various health professionals and had 2 MRIs plus other scans and x-Rays..... Everything normal. I am now seeing a chiro who thinks that it is a sacroiliac problem with trigger points in the surrounding muscles. Question... Could a problem with the sacroiliac joint and trigger points affect the sural nerve thereby causing localized pain AS WELL AS pain in my foot?
