Hello @missingthebeach and welcome to Mayo Clinic Connect. Your symptoms improving as a result of your antibiotics seems to point to some type of inflammation/infection that was reduced after having taken the antibiotics.

First, you will notice that I have moved your post into an existing discussion on the same topic which you can find here:
- Could this be chronic pancreatitis?: https://connect.mayoclinic.org/discussion/could-this-be-chronic-pancreatitis/

Members @tinatoren and @susanh824 may be able to come back and share their experiences.

Have you done any research into gut health and microbiome to see if you could potentially achieve some additional improvements?

@missingthebeach,
Wow, my symptoms are also similar to yours. Last year, under Chiropractic care for back issues I had several CT and MRI scans in which the Radiologist noted an "enlarged pancreas". My PCP ordered a pancreatic MRI to be prudent and found a mass-like area of enhancement on the head of the pancreas and enlargement. This started a whirlwind of events including an Endoscopic ultrasound with Biopsy to rule out cancer, a new diagnosis of Chronic Pancreatitis cause still unknown and an episode of acute pancreatitis after the biopsy which put me in the hospital for a few days. My labs are mostly normal except I have a positive ANA. I have the extremely low body temperature in which I simply cannot warm myself back up, constipation in spite of oral fluid increase and a healthy pancreatic diet and the pain under my left breast or just over my pancreas. I went thru a 47 day Steroid Trial and just had my follow up MRI last week. This test was supposed to confirm that I have Autoimmune Type 2 Pancreatitis...however, my GI called today and feels that there was no shrinkage to the mass, which the biopsy said was negative for cancer and the report said that my pancreatic cells have been severely reduced and replaced by the fatty cells which is a decline from the last test. This is not an indicator of body mass, because I am underweight, instead when the pancreatic cells begin to die, because the pancreas is attacking itself, the cells are replaced by "fatty deposits".
In your case, I would absolutely insist on imaging. If you have pancreatitis, you may not have any change to your labs if it's caught in the early stages. Unfortunately, we must be our own advocate because the physicians have their own agenda.
My GI is sending me to a Pancreatic Specialist because clearly something is wrong with my pancreas but we've ruled out cancer for now, autoimmune, alcohol, and obesity. He acknowledges that having Chronic Pancreatitis puts me at risk for cancer at any time and will continue to order imaging every 6 months.
Hope this helps and I wish you the best in your journey.

From what I read from your post the color of your stools that says to me liver I had hepatitis c. I have a fatty liver and problems with the circulation to it from my hepatitis. Not to mention I ate Tylenol and Motrin like it was going out of style which I wish I really understood. I mean I knew that it was bad for you but didn't really get it. If you know what I mean, how horrible it is. You know when you're young, nothing ever touches you in your head. At least you think it doesn't right? So I'm having the same issues. They're testing my pancreas. I was on ozempic and when I had the shot it seemed fine. Then they changed me to trulicity made me feel horrible in my stomach and then the pill that is the same medication that's and it was empty. It made me feel even worse in my stomach bloated like I was always full. Also, I related to the feeling like my insides are being eaten like I'd be so hungry. At least I thought I was that it burns. My stomach was on the inside out. Now I thought it was my surgery I just had on my lung. Part of my lung was dead on the left side and it always felt like there was a hand inside my ribs because they cut out part of my lung but it started swelling recently in that same area. Not to mention back pain constantly then they thought it was my kidneys which I do have blood in. So they've given me multiple antibiotics and I've become well, not myself. But whatever I have is antibiotic resistant blood in my stool and whatever came out of me. The other night was like rainbow colored crap. Pun intended and it hurt right above my belly button right underneath my sternum and I've never felt that kind of sharp pain in my life before. Honestly what I have learned from everything I've looked up your liver, your lungs and your kidneys and I guess use your pancreas are all related. You do damage to one. There's damage to all of them going to be done so you can't just say it's one single issue because it can affect everything else in your system which is what I'm having problems with and pain. I have become almost bedridden cramps in my legs especially today. I had rabdo but I hadn't had cramps like this in years. I could not stand up but I'd lay down. I'd have to jump up just to get rid of pulling muscles in my calves. My suggestion is one thing that got rid of everything on my stomach was probiotics the vegetable kind the ones that are fermented I heard that they do wonders and I've seen some of it happen. They've made me feel better in my stomach in some ways. Also keeping my liver as healthy as I possibly can. Even though it's already been damaged. Your liver can heal but you can't heal your kidneys. And if your liver's overloaded it's going to directly affect your kidneys because if it can't process it and tries to go through your kidneys, it's just going to kill your kidneys and there's no coming back from that. So try to clean your liver out as much as possible. I've started it a regiment of things like making sure I have enough electrolytes taking fiber because I've heard it's like a little broom for your liver. It'll help sweep things out but you also want to help it get through your kidneys. So lemon water, cucumber water hibiscus tea Ginger all these things can really help, but you want to check with your doctor because some of them especially hibiscus tea can be very strong and sometimes maybe hurt you more than it does good. I drank a cup for the first night and it was unbelievablely overwhelmingly strong so maybe just make it light and just drink a little bit here and there. It lowers your blood pressure cleans out your liver also helps. Vitamin c helps your heals your liver. Cleans out your kidneys and your lungs. There are a lot of home remedies that are probably better than all the medicines that they've been giving us all the time that cause more problems and it's just one medicine to cover up another medicine symptom. Try to detox yourself from all that I know I am. I've come to the realization that I haven't been an addict when it comes to trying to fix everything with a pill and it just doesn't work that way! But my suggestion for you is for them to go after your liver. Check it once. Check it twice. Keep going to another doctor. Find a second opinion, even for your pancreas and gallbladder or whatever it could be. Don't just take one doctor's answer because they might not necessarily have the right one. Don't give up on it cuz you think you might be younger than me and I'm only 42 and it sucks feeling like this like you're 80. So let me know if you feel better or if something works for you cuz I would love to try it!
