Help! Tell me I am not going crazy

Hi All,
Thanks to all that replied to my "Biochemical Recurrence" post. You are all appreciated.

I reached out to my PCP about a referral to a medical oncologist. Here is my two most recent (9/24 and 4/26) lab results for my PSA. Remember, I had a prostatectomy in September 2015 and sRT in Jan/Feb 2017. My Gleason Score was a G9 with small positive margins (< 1.00 ng/ml)

4/26 0.327 ng/ml Reference Range < = 4.00 ng/ml
9/24 0.064 ng/ml Reference Range < = 4.00 ng/ml

Here is my PCP's response:
"PSA is normal. I am not concerned"
He does know that I had prostate cancer, surgery and radiation.

I requested him to send a referral to a medical oncologist as I think he has forgotten my situation. I am not going out of mind, right? This is a serious situation, right?

Thanks All.
