I can't believe i just read your message and you describe exactly what has started happening to me. only sometimes and always when im in a sitting position, usually where im quite tucked over. suddenly it feels like an organ pops out from under my rib cage. its very painful and uncomfortable. after about 20 seconds it goes it feels like it gradually moves back into place. i too have had three children.
Also by pregnancy number 5 the one I lost actually saved my life. I had not been feeling great but my stubbornness and responsibility kept me pushing thru, I had been to several doctors even brought in by ambulance and released finally my husband took me to the next town's hospital. They did not see anything thru sonogram other than the fetal pole, they decided to do lab full panel, I had only 7 liters of blood in my entire body and leukocytes where high. Back into surgury.! I wake with a tube hanging out my stomach. So it was found that due to diverticulitis I had a pouch inflamed in my intestines and it was leaking into my abdomen, my body was trying to fight to no avail. Unfortunately baby had passed 2 weeks before. After all said and done I have an umbilical hernia, lesions on my liver. ulcers on my esophagus, that's a whole another story... but for those with chest pain and gerd mine was found to be ulcers on my esophagus feels like a heart attack when spasms happen. I still have the feeling of something moving flipping or getting stuck on my right side idk if diverticula is going on or what I will be going back to doc. it's been yrs since all this but symptoms have started back which caused me to search and find this discussion. Maybe i should not have ate that popcorn months ago... Sounds crazy but they say it's bad for diverticulitis.
I've had this as well. Mine happens on my left side though, not sure why. I do feel it, sort of in the right side, through my rib cage. It's more of a feeling rather than pain, and there isn't any pressure on my side. I've had it for a few years now. I do think it's a hernia though, since I'm seeing scar tissue. I'm not sure how I'd get a hernia when it happens to my left side. I had a rough pregnancy with my first and I had a lot of labor pains, but no delivery. This has happened once in the past, but it's nothing like now. It happened to me once, and I was in the hospital for a week. I was actually pregnant with my second child, and I had my gallbladder taken out because of the pain. They had drained the area before the surgery, so it wasn't a hernia, or anything else. It all started after I had my gallbladder surgery. I've had it since then, and it hasn't gotten any better. I'm sure you know what it is, but I just wanted to say that if you have this, I hope you get some answers soon. 827ec27edc
