Dr. Tim Taylor, a chronic pain specialist, wrote and maintained a section of a the trigger points tutorial on this website for a few years, about medical factors that can make trigger points stubborn. He and his wife Dr. Bittner were pain management physicians at Pain Relief Home in Richmond, Virginia, and both former chronic pain patients themselves. Their practice is now closed and I have lost track of them since about 2014.
