What should I do-advice please

hi All, so I’m 44 and for the last few years have had on and off pain in my lower abdomen and pain in lower back and tip of penis. My dad sadly died of prostate cancer at 64 having been diagnosed 2 years previous with metastatic PC and had all the treatments going but nothing worked. When he was diagnosed they advised I get my PSA done.I have a PSA every year and always been 0.45ish . Ive had an ultrasound and went to see a uro because of the pain I was having at that time and to put my mind at rest re PC Also had DRE.  I have some calcification of the prostate and he said my prostate was slightly enlarged but felt fine and nothing recommended Other than yearly PSA.

since then I have continued to have pain in groin or in my penis sporadically and a pain after but not during peeing, it goes away and it’s manageable so I don’t stress 4 too long. for the last month the pain after peeing has been there and I now feel as if I need to pee but don’t. I only get up for a pee once during the night now and again but the feeling as if I need to go is new. I went to see the doc recently but it seemed pointless, he just confirmed the PSA was consisten, the DREs have been fine and the uro I saw said wvwrything is as it should be at my age. He prescribed tamsulosin but it’s not doing much good and it just makes me stress and I’m constantly aware of this feeling now. My question is what more can I do , i just feel it’s pointless going to the gp, wondered if I should go private and see a uro again, get a ultrasound etc etc so I’d appreciate some advice
