Continuing “Un-explained Event” – Urethra Pain

Hi All
I am a 44-year-old male that has been experiencing an abnormal unexplained urethra pain. I have been seeing a Urologist since it has started, but have begun to reach a point of “it must be all in my head” explanations.
This is not the first time that I have felt a pain in this area. A year ago while finishing using the bathroom, I began to pull up my pants, I had a sharp pain on the tip of my penis when I pulled up my underwear. From that point it was painful to even wear underwear and so I decided to see a Urologist. The doctor did a few tests and the only thing that he could come up with was that I had a little fat in my liver. A few weeks had past and I was back to normal. A year later and I am now experiencing something similar in the same region.
The pain that I feel now started on its own out of nowhere has been the longest ongoing pain that I have ever had in my life with no explanation. It has got to the point that I pray for something treatable to be found, just so that I can have some relief. It is affecting my home life as well as my work. I do not want to exercise because of the pain of tip moving against my underwear. It is going on almost 2 months now. There have been no traumatic injuries or events that I can remember that I could say could be the cause, but one. About 10 years ago I was exercising with a friend and ended up falling backwards and landed on my butt when my foot got stuck on the equipment. I have had no prior issues since then and only one hospitalization which was covid related – dual pneumonia.
The symptoms started after I was doing more dribbling after peeing. When the pain started it seem to be centralized at the tip and shaft of the penis, possibly testicle. I can push down on the area and not feel any physical pain so it is hard to pinpoint. I have this urgency to pee, a no relief feeling after peeing, tip is sensitive, there is this feeling that I have to clench to hold back from peeing at times. One of the first things that was prescribed to me was an antibiotic, Ciprofloxacin – 500MG. I was still having the same issues past a week so the doctor decided to put me on a stronger dose of Doxycycline Monohydrate – 100MG. I took till the prescription ended. I am also taking Myrbetriq for my overactive bladder. I have this uncomfortable feeling after urinating. It seems like a roller coaster. There are days that it feels a little better, but other days it feels like it is day one. This makes me feel like I am trying to heal, but unable to for whatever reason and thus why the pain is up and down.
Urologist has run multiple tests. Verified that my bladder is in fact emptying out. Checked my prostate, performed a cystoscopy and found no scarring or other issues with urinary tract. Performed a urinalysis at every visit. At this point he advises that I should consider physical therapy, pelvic floor exercises. I am considering getting a second opinion. This issue has been ongoing and I am starting to lose hope. I appreciate any information you can suggest, I know that I can not be the only one experiencing this.
