You probably are guessing correctly. I had burning like you mention for a good year. It was a stricture and was corrected by opening it up. Flow improved for 6months or so and has slowed up some, but no more burning.
I did not have surgery,but the problem is the same from irritating the urethra.
Diagnosed with a Gleason 4X3. Second opinion at Stanford came back as 3X4, 1 out of 7 samples, Left Side. DRE showed Normal. Before Biopsy Psa gradually crept to 10. Dropped to 6.4 with Alt. suppliments.
