Pain specialists are under pressure for various reasons (this is no excuse for doctors) to decrease the pain of patients over time. Patients who constantly tell the doctor a pain scale or a level of pain constantly high on the chart, many doctors will react negatively to the patient. If the doctor feels there is little improvement in pain over a period of time then why bother. Those with RSD and other severe chronic pain patients are in a tight spot for sure. If you tell them you feel much better, your visits could end. Tell them you feel constistantly like hell your visits could end. Many patients then realize it's some sort of game, many play it then find themselves looked upon as a drug seeker.
Those who are very wealthy don't have to worry about this. Believe you me, there are no RSD suffering multimillionaires, and they do exists.
