Help; Sudden onset of excessive belching, odd abdominal pains.

[nh_user_1420524]

Hi, I'm trying to see if **anyone** on here has had similar health issues and can point me in some direction so I can go to a doctor, get tested, and potentially get treated. So much has been ruled out, so I'm trying to see what all is left that I can be diagnosed or tested for. Me: I'm a **28 year old male**, eat a fairly healthy diet, weigh 150 at 5' 8", drink plenty of water, and am usually fairly active though I haven't been to the gym since the pandemic started. I'm not a smoker, I don't drink pop/soda almost at all (with the exception of like 1 bottle every month or two), and I only have like a bottle of cider or glass of wine once a week (if not every other week). Since December, I've experienced the sudden onset of **abdominal pain, belching, and random but occasional constipation.** I've been seen by multiple doctors, and they've determined I have a normal gas pattern, no abdominal free air, no calcifications, no masses or tumors, etc. Bilirubin, glucose, ketones, leukocytes, nitrites, protein, urobilinogen, and more are all normal levels. **Symptoms:** * Abdominal pain: Random pressure, sometimes jabs of pain, sometimes it feels like everything is moving down there, and sometimes it feels like a low-voltage shock. Pain is primarily in my Lower Right Abdominal Quadrant though I can experience the pain throughout my entire abdomen or my solar plexus region. * Belching: I'm not a person who frequently burps, and since the onset of this I can belch up to 20 times an hour. Not just little burps, but long drawn out belches. It's not even so much as a choice as it feels like a reflex. * Constipation: Again, random but occasional. Most often in the evening. Most days I can go in the morning, though after around 4 PM it becomes near impossible to get anything out. When I do, it's akin to rabbit pellets. It can also take me up to 1-3 days to fully process foods out of my system (based on what I ate versus what's present in my stool) **Things that doctors have ruled out, or believe to be ruled out;** * Hiatal Hernia * Kidney stones * Gallstones * Gallbladder disease * Kidney disease * Tumor(s)/Mass(es) * Liver damage/cihorisis * Liver disease * Cholelithiasis * Cholecystitis * Appendicitis * and a few more things I'm sure **Tests Done:** * Blood Test * Comprehensive Metabolic Panel * Hepatic Function Panel * Urine Test * Multiple X-Rays * Multiple Ultrasounds * Physical Exam So my question, does anyone have any idea what I might have wrong with me? It's wearing down on my mental health because it's gradually become more and more present, and my concern is that I can keep seeing doctors, all my tests can keep coming back as "unremarkable", I can keep racking up medical bills, but I'm just going to have to wait until this becomes so bad I am rushed to the ER so they can find out what's ruptured or gone haywire in my body.
