Why doesn’t it hurt to pee?
I’ve heard that when someone gets something done (medically) to their urethra, it hurts really bad. What I mean by that is when doctors have to put a camera up the urethra. If that’s the case, then how does peeing not hurt like hell, I mean, there’s fluid coming out really fast and there’s pressure there so? It might be a simple answer but I’m pretty dumb and have been wondering this for a while.
Edit: Yes I’m aware that this was a dumb question. As I mentioned to one guy who commented, I didn’t think this question through thoroughly as I got back from work before posting this and was exhausted (I still am honestly). If you don’t have an answer or anything nice to say, don’t say it, kindergarten shit people. Thank you.

Not 4 posts above this one, I read a comment on a post about 89 liters of Sunny D, and the commentor said they drank so much Sunny D that it hurt to pee. Have you been drinking a lot of Sunny D?
Peeing can be uncomfortable sometimes, if i really have to go badly and its really dry outside it feels like the skin is getting rubbed before the flow begins, ugh 🙁
Wait?! It shouldn’t hurt to pee?
I’ve had several procedures where they had to go in via the urethra. There are two main reasons it is uncomfortable and may hurt while urine coming out does not. The first is simply lubrication. Urine doesn’t require lubrication to come out. It just flows across the surface of the urethra. It is soft and shapeless and doesn’t offer much friction. Sending something solid in requires lubrication or it will snag and scrape on the surface of the urethra. The doctor will inject a lubricate and numbing agent to help overcome this issue. Of course he does it by stuffing the dispenser in which means putting the lubrication and numbing agent in is itself uncomfortable.
The second is there are sphincter muscles that need to be passed thru. When you urinate it comes out because your body relaxes those muscles and opens them up. We don’t typically have the ability to relax them on demand for something to go in backwards. That means the doctor needs to forcibly shove thru the sphincter which will be trying to remain closed and will squeezing against the item passed in. This can be very uncomfortable and sometimes painful. These are not muscles that experience this kind of an event ever so the nerves are not used to it. They signal to the brain something is very wrong which the brain interprets as pain.
Curl your fingers to touch your thumb and then find a hard object about that same diameter. Now close your fist tight and while keeping it as tightly closed as you can, ram that object into your fist to force your fingers open. Without lubrication this is going to either fail entirely or hurt a lot. Now add lubrication and try again. You probably won’t fail this time, but while the object is in your hand continue to try to squeeze your fist shut as hard as you can around the object. You will quickly find the muscles in your hand start to cramp and trying to squeeze against it is uncomfortable or painful. This is what is going on with the sphincter muscle between your urethra and bladder that holds back your urine.
I’ve had a catheter in the past and it didn’t hurt going in or out. Maybe uncomfortable but not as bad as the pain of a full bladder and not being able to pee
Ive had a camera up there (cystoscopy is what the procedure is called) , and to be fair going through the urethra wasn’t that bad, just uncomfortable.
When it had to go through the prostate though…my word that hurt.
.. wait it doesn’t hurt when you pee? :’)))
The camera doesn’t hurt. I’ve had it done several times. It’s mostly just a weird pressure being applied and they use lube.
I had a urethraplasty surgery (they replaced a part of my urethra with a graft from the inside cheek in my mouth). The most painful part of the surgery was my mouth. The cameras and catheters were never really painful, and peeing after having the camera or catheter removed was just very minor irritation.
It hurt like absolute hell when I peed when I was having my problem, though. I had scar tissue building up in my urethra and it was blocking the flow. The doctors said the pain was worse than the pain while passing a kidney stone. It was causing my kidneys to start to fail also.
Huh? It always does. Except when it isn’t red.
Why does a shower of rocks hurt while a shower of water doesn’t?
