Anyone with high prolactin? How high was it? Risperidone?

What was the diagnosis?
I had my hormones tested and prolactin level is high. I was expecting it since I'm having Risperidone. But the doctor says it doesn't go this high even with Risperidone & has referred me to an endocrinologist saying I "might" be having a benign pituitary tumor. My level is 3643 MicroIU/ml
