Pain, please help.

I'm sure I am not the only one experiencing the pain I have n I would love input n possible ideas that will help. Prostate Cancer- November 2021 I had Prostate removal; after removal there was Cancer in the margin so the Cancer was still in the area. November 2023 I had Chemo-hormone injections for a year as well as 26 rounds of Radiation, to remove remainder of Cancer. Thank God the Cancer is gone but in February 2024 I started having pains n burning in my urethra every time I had to "go" and also at times when I wasn't. Doctor has checked everything, no kidney stones, no UTI, and they even ran a camera down my urethra to my bladder and found no issues but I still have pain always n this past week, the pain has been worse n seems like I always feel like I have to pee. I've been dealing with this pain for a year now n it's not getting better, just worse. Is there anybody out there unfortunately going through the same issue?? Anybody that has n it's better now, how?? Thank you for reading n God bless you all 🙏✝️🙏
