I'm Concerned About My PSA

hello, good people. on feb. 28th, 2019, i was diagnosed wit' GS 4+3 = 7 PCa. as a form of treatment, on jan. 9th and 23rd, 2020, i had HDR brachytherapy and finished up six months of 50mg. bicalutamide. my PSA at diagnosis was 11.9. thanks to COVID-19 i had to wait a year before i was able to have my first PSA blood draw. my first PSA in jan. of 2020, was 4.04. six weeks later, it went down to 1.51. then, three months later, it was 1.52. this past september, my most recent PSA was 0.55. on the 25th of this month, i go to have my next PSA.

over the last couple of weeks, i've noticed my urinary streams in the morning are getting a little weak. i haven't had a weak stream since late 2020, when i was still in the healing process. fellas? i'm starting to get concerned about my PSA. back in 2014, i was diagnosed with BPH and asymptomatic inflammatory prostatitis. so, i was thinking maybe that could be a cause for the streams being weak at times. either way, i'm concern'd that the weak streams may have a negative impact on my next PSA. what R your thoughts on this matter?
