This year I told my Neurology Dr about this because I thought it might be linked to my Multiple Sclerosis. I was reading about the bladder issues that MS causes & it sounded like what I'm experiencing. I'm fairly certain that it is something to do with my MS or my type 1 diabetes, either either, I don't care, it's just super annoying.
My MS doctor sent me to the Bladder Dr(Idk the name of the department), & they got me to come in with a full bladder. They did quick ultra sound to make sure my bladder was super full. Then I had to pee on this chair which had a bowl on a measuring scale thing under it. Then they did another ultrasound to see if the bladder was totally empty or whatever.
After this the DR took a look at results and I went back for follow up app where they told me about results and what they thought etc.
Basically they said that my bladder was full and when I peed, I peed like normal but there was pee then a few mins of nothing & then more pee. And after then they took second ultrasound, my bladder was empty.
I said yes that is what happens every time I pee, just like what I have been explaining. I pee and then when I stop, I have to be careful bc that doesn't mean I'm finished, there is more pee and I have to make myself pee the rest. If I don't I get this awful feeling where I still really have to pee and it goes on for ages and is super uncomfortable & painful and I can't go too far away from the bathroom. It takes ages & many trys to basically get the pee out. It is quite debilitating. However if it gets this bad, the only thing I've found that helps the situation is to drink lots & lots of water to make myself for sure have to pee again with a full bladder and when I go pee again, I have to make sure all the pee is peed. I have never said pee so much before in a conversation! Anyways I explained all this again to this Dr about making sure I have peed everything & what happens if I don't & how I had told MS Dr & he sent me to them.
The bladder Dr said yeah basically what I'm doing is what they teach people to do if they have this issue. It's just an annoying issue with the nerves in bladder & they don't for sure know what causes it cos it could by my MS or t1d however it can happen to other people who don't have either of those things as well so they just aren't sure.
Anyways, if you are having this issue or similar, you should def tell your Dr cause it's so inconvenient & annoying, you shouldn't have to be going through it! They can investigate & hopefully help you. Don't be embarrassed, the Dr won't laugh at you!
I really hope what I've explained I do will help someone too.
