The biofeedback seems to have picked up on some different things but like you said, hasn't given you a clear answer of the cause. I don't know how interested you are in vega testing or muscle testing but I this is how I found out about all of my health problems and the root causes (EBV, mercury, compromised pituitary gland).

My mother was also mercury poisoned from her amalgams and was hospitalized for it. She had some omega testing done and the two things that showed up most were mercury and teeth, she had a mouthful of amalgams at the time. She got them all out and is quite a healthy specimen today.
