My wife was diagnosed with "thoracic duct outlet syndrome" when a teenager. Years after we married, I was diagnosed with carpal tunnel syndrome and had a tunnel release. My wife noticed my symptoms were the same she had complained about two decades earlier. She had permanent damage to the ulnar nerve by this point so when she visited the neurologist, the evoked potential test showed no response. The tech had never seen that so she called in the physician and they proceeded to ramp up the voltage till my wife, tears in her eyes, began begging them to stop.
