I'm a Medical student with the same problem described here and I will do my best to explain what is going on. Occasional sharp pain aggravated with urination and or stretching of the abdomen. Relieved by hunching over. There is a ligament that connects from the bladder to the umbilicus called the median umbilical ligament. As a fetus this structure is called the urachus and is essentially a tube that drains urine back into the mother through the umbilical cord. People that are experiencing the type of pain described here on this forum likely have remnants of the urachus. These remnants present as pouches (cysts, sinuses, ect) that become easily irritated. Here is my reasoning. When the bladder is emptied it becomes smaller and is "pulled" deeper into the pelvis. This in turn pulls on the median umbilical ligament that in our case didn't form properly and can be described as a urachal remnant. Back extensions or popping out the belly would reproduce the same symptoms as urination because once again that structure between the bladder and umbilicus is being stretched taut. In my experience I get this pain after vigorous exercise for long periods of time where my abdomen is being stretched or twisted. Many people on here refer to this pain as a pulled muscle, but I don't think that is the case. This pain comes from below the rectus abdominis (six pack muscles). Unfortunately this is just something we must put up with i'm afraid. That is unless it becomes constant where potentially an abscess forms. An abscess can occur anywhere in the body and is essentially a walled off isolated infection that antibiotics for the most part cannot get to and therefore must be surgically drained. The only solution would be surgery and in my opinion the risk of surgery for this problem is simple not worth it. Here is a case report of this exact problem with pictures to help understand what is really going on. Hopefully this gives people closure. http://www.ijars.net/articles/PDF/2145/19570_F(P)_PF1(Om_Vsu)_PFA(GH)_PF2(VsuGH).pdf
It's not a UTI. There's actually no infection. I know many people who have had UTI's in the past, yet no one has experienced this pain. With all of my google searching I believe it could be Painful Bladder Syndrome.
What I was worried about is whether the bladder is actually full during the episodes (which worried me immensely), and once we were on vocation and I got the pain and it was quite strong, and I was quite worried, because it was the longest episode I have had and we were away from home with lots of people around, so I didn't have a safe spot to just lay and do my thing without being bothered, or being seen hunched over!
My big worry was basically, ''Is my bladder actually full right now, or did something else trigger it?''. We ended up going to the hospital a few hours later, all the while I hadn't peed at all, and the doctor did an ultrasound scan of my bladder area, and gave me a strange look and said ''it's completely empty...''. I have to mention by that time it had pretty much gone away, and the look on the docs face was basically ''Are you kidding me? Did you just make that sh*t up?'' That experience proved to me that the bladder isn't necessarily full every time you have the pain.
I'm 19 male. I don't think gender has anything to do with this, it has to do with the bladder being connected to the urachus, which can happen to either male or female, and the differences ''down there'' don't come into play at all if you think about it. it's to do with how the bladder relates to the abdominal area around it, and the urachus, so whether you have a penis or a vagina doesn't make a difference. The best response so far has been from the MD above, it makes perfect sense. Search for me on the famous social media sites with the words 'face' and 'gram' in them, by ''swansea road bikes'' and swansea_road_bikes respectively.
Anyways I've developed some (presumably unrelated) pelvic pain as of late and was referred to a physiotherapist that specializes in the pelvic floor. Upon examination she noted that my pelvic floor was way too tight and constantly being tensed. Over the next few months of physio she taught me to relax and stop tending my pelvic floor. I can now tense and relax it on command.
Why am I telling you this? Well, the dreaded pain hit me a few months ago after I had spent a half hour chipping ice off of my sidewalk. It was probably due to the fact that I was not drinking much water that day, combined with the strenuous work.
One thing I noticed when the pain began to get bad was that if I tensed my pelvic floor as i was trained, it made the pain worse and/or trigger it again. My hypothesis is that your pelvic floor muscles are intimately involved with your bladder. When they spasm or cramp (because they're held so tight) they pull on your bladder which also pulls on the umbilical ligament. So, naturally if you can learn to relax your pelvic floor muscles and keep them from cramping or spasming, perhaps the belly button pain can be prevented.
Looking back, as the pain became more frequent I would tense up more and more all the time to prevent it, which becomes a vicious circle as that can potentially cause more spasms.
Anyways I'm not a doctor or any kind of medical specialist, these are just my observations. If you can find a sympathetic and understanding physiotherapist that understands the pelvic floor try talking to them about it and see what they say. If they check your pelvic floor and it's super tense there's nothing to lose by learning to relax it. After going to so many doctors who basically said nothing was wrong I realized I should have gone to see a physio years ago. I had no idea what they did.
Another thIng that helped lessen the occurrence at least for me was regular massage if my abdomen, especially skin rolling. Look up what fascia is- dealing with the fascia on my abdomen, especially the area around my belly button has helped me feel more at ease.
My best wishes to all of you, I know how awful this can be.
I'm having this excruciating, string-like pain from behind my belly button to my urethra (only when abdomen is stretched or I try to pee) for the first time since going vegan. Might be worth noting that I went with my sister to a froyo place last night, and seeing that they offered non-dairy, had some myself. Probably a lot of refined sugars were in there. I'm going to avoid that sh*t like the plague now, since noticing I've had none of this pain when I do so.
If it keeps coming back, my thinking is the umbilical hernia / endometriosis explanation makes more sense. I will see a doctor next time this happens, if I can't connect it to sugar aggravating yeast bacteria or something.
Found this interesting paper written just recently. It doesn’t describe our pain but it does discuss the pulling pain from belly button and Urachus. Thoughts? https://www.hindawi.com/journals/criem/2018/6051871/
