Classic results, normal scans, feeling defeated

I have high PTH, high calcium, low vit D, several symptoms listed, and the scans I have had done show nothing. Ultrasound was normal, sestamibi scan was normal, and now the doctor is ordering a CT scan. If that is normal I guess my next option is exploratory surgery?! I have read everything I can find about having symptoms and other things that could cause the blood results. I have an appointment with an endocrinologist but it is a month away. Any suggestions or similar stories would be much appreciated, very nervous :(
