Additional information: Caller stated she received a Pfizer covid 19 vaccine (2023-2024) (12 years and older) on 03Oct2023. "Shortly after and is still happening I started having if I ate much of anything like bouts of diarrhea and it's really dark. Yesterday I ate cheese and crackers, last week I was only eating bagels with nothing on them. If I ate much of anything this happens. Friday night I went out to dinner, didn't ate much, brought leftovers and ate them on Saturday, I was just miserable with diarrhea yesterday. Today I don't know what is going on, I'm having stomach pain and abdominal pain. I'm really not feeling well, that report took forever, because I'm on a lot of medications. I've been disabled since '91, and I've developed several other problems since then, so I had to give her all the medications. I'm failing here, I really am, today I'm not feeling good, my stomach is really bothering me. I don't know what this is about, I hope is not problems. I have awful diarrhea, I'm almost afraid to eat, I used to be a milk drinker, but I don't do it anymore because I'm afraid is going to trigger things. Mine is like severe, do you know how long they had problems with it. I had this vaccine on the third and today is the 16th, so I've been with this for almost two weeks. This is the first Pfizer vaccination I've taken in the past I've taken Moderna, the first 2 vaccinations and then 2 boosters, were all Moderna, when I went to the pharmacy they only had Pfizer, I don't know if this makes a difference or not. Mine is severe and it is very dark, almost black, I've never had it like this before and today I had stomach ache and abdominal pain I just took some medicine, I hope it's not going to start again. I don't know what I can do about it, the pharmacist said I can try to take some Imodium and I just took some because my stomach is bothering me, I don't feel good. I'm at the point that I'm afraid to eat much of anything. I've been putting it off, I just thought it would get better, but when I eat much of anything besides dry bagels or crackers or toast I end up having an issue and I just hate it. I went through this as far as two years ago with a medication I was taking, it was bad, I had severe diarrhea, it was not a good situation. Yesterday it went from morning to some time in the afternoon, I thought I was going to lose my mind. I have other medical problems. I have a lot of pain to begin with it. It could be interacting with one of my other medications but I have not idea which one, I'm on a lot of medicines, some of them I only take when is needed but still I'm on a lot of daily medicines. I have been having bowels since I got this shortly after I got this of like real dark colored soft stools diarrhea and I can hardly eat anything okay, otherwise it's just terrible. I ate one of my first meals on Friday because lately I been eating dry bagels may be toasted and cheese crackers and cheese and I got really, I did not get sick Friday, but I have same meal on Saturday and I had a really hard time. Today my stomach is bothering me. I mean I can eventually eat some crackers and cheese last night may be that was just too much. I mean I am having a hard time eating anything because I am always afraid that I am going to have another episode. I got this to report.

Treatment: Consumer stated, "No, well no I shouldn't say that. I tried the dicyclomine but that wasn't very helpful.
