Insulting Assumption

Anyone else ever had the experience of being told that their undiagnosed chronic pain is psychosomatic? "It could be referred pain, or it might be imagined." How insulting is that? I've had chronic pain in my lower right inguinal region for three years. I have had three sonograms done to try to find out what the heck is causing the pain. Nobody can find the source. So when confronted with their own inability to discover the problem, some doctors have had the audacity to blame it on my mind. Say what???
