Wow - well, since this has been going on for some time now & doesn’t seem to be getting better, it may be time to see a specialist. I wonder if your Urologist or Surgeon can refer you to someone who specializes in difficult cases like this? I certainly wish you the very best in your quest to get to the bottom of this. I can only imagine how disruptive this could be to your normal daily functioning. Please let us know what you find...
Hello and welcome to the forum. I agree with BonzoDog and appreciate his response. You've had surgery and with that comes swelling and bruising. How long ago did they remove the catheter? This is most likely normal post operative discomfort and issues but please check in with your doctor to confirm. https://my.clevelandclinic.org/health/diseases/15537-urethral-stricture-in-men Best to you.
I would just speak to your Urologist/Surgeon about this - it's possible this is not an uncommon complaint in the first few weeks following surgery. Let us know what you find out...
