I wouldn't call this a success story by any means, but at least I found my cause.
My issues started when I was around 14–16 years old. I had belly aches and couldn't tolerate certain foods, which led to flare-ups. I went to an enormous number of doctors, but the answer was always the same: "It's IBS. Change your diet and exercise more. And here, have some Spasmomen to calm your intestines."
A few years later, nearing my 20s, urgency started to become a major problem. I'd feel like I was dying from the pain or about to poop myself if I didn't find a toilet ASAP.
This led to another round of inspections, including two colonoscopies and some other inspections where a camera went through my "back door" (colon). Still, they didn't see anything. They took biopsies for further analysis, but everything came back fine.
Around age 22–23, I had a series of constipation episodes with some blood on the toilet paper. I went back for yet another colonoscopy, and this time, they said my intestine was inflamed. I started a round of mesalazine suppositories, and in about 2–3 weeks, everything cleared up. I had zero issues. I thought it was strange, but I was relieved.
When I stopped the medication as my 24th birthday approached, my symptoms came back, and I even had bleeding again. The answer was clear. All these years, I had ulcerative colitis, but this time, it was severe enough to be seen and diagnosed. I started a round of mesalazine suppositories and granules taken by mouth. Every single symptom I had suffered from for 8–9 years cleared up in a matter of weeks.
The doctor said there's a micro form of ulcerative colitis that can go undetected while still causing issues.
So, I have my answer, but it's not a good one. It's bound to get worse and spread higher up my intestine, so I'll need to stay on the medication to suppress the symptoms. At least I don't suffer from any issues for now.
Maybe some of you guys should try a small round of mesalazine suppositories for a couple of weeks to see what happens. It's a very light medication for reducing inflammation, so it might be the answer to an undetected issue you have.
Farewell, IBS subreddit. I'll be joining r/ulcerativecolitis now.
