Please help!!! I’m so worried!!!

Last year in March, it started with the feeling I need to go….sit on the toilet nothing would come out. Fast forward a year later I am having horrible lower abdominal cramps, now almost consistently. When I sit down I feel like pressure like poop is stuck but I am still not able to fully evacuate. It’s never ending for. Year now but the cramps I didn’t have before. I am petrified. I had a colonoscopy in November they didn’t see anything. What do I do? Is this IBS?

I have symptoms like that and feel like it's probably related to my prolapsing bladder, pressing on my lower intestines. I have to bare down to poop, even when it's really soft. I don't know how old you are, but I really feel like all my internal organs have dropped and are probably always pressing on each other in my older age (74)........making it harder for poop to come through easily. I would be sure I was eating enough fiber, and also maybe adding 1 drink of Miralax every day. Also, maybe do some kegel and lower abdomen strengthening exercises. Hope this helps.
