@cristina9532 - Hi and welcome to Mayo Clinic Connect! I understand how worried you must be to see your father having undiagnosed abdominal pain. Your FP did not order any tests? I agree with you that your father should have more diagnostic tests done. I can think of abdominal ultrasound, CT, lab work and EKG.
Remember, we are not doctors, but members who have gone through various difficult to diagnose illnesses or more common problems wanting to connect with others.
I can’t tell you where to go, but he needs someone experienced in Internal Medicine. If you have a major university hospital nearby you could call and get an appointment. Obviously, if the pain gets bad enough, he should go to ER where they would do a lot of these tests.
I hope he can be seen soon- unusual to have abdominal pain for so long.
Can you get back to us when you know more?

Hi @cristina9532 – I would like to add my welcome to Connect along with @astaingegerdm. Thank you for advocating for your father. Here is some more information you may find helpful - Abdominal Pain Causes by Location: Upper, Lower, Left, Right: https://www.medicinenet.com/abdominal_pain_causes/views.htm.

I agree with @astaingegerdm that it would be good to seek treatment at a large teaching hospital or health facility like Mayo Clinic. If you would like to seek help from Mayo Clinic, contact one of the appointment offices. The contact information for Minnesota, Arizona and Florida can be found here http://mayocl.in/1mtmR63.

You mentioned that your father is very fit and the pain usually comes after some physical effort. Are you able to keep track of the physical activity your father was doing before the pain occurred? That might be good to provide to the doctors.

@cristina9532 - Thank you for getting back to us! It does not sound as if your father is worse, thank goodness. I hope you get to see your GP as soon as he is back. You seem more confident now knowing what to do. Are you using the German Health system?

@cristina9532 - If your father’s symptoms are not improved with the new medication, you should go back to the doctor and request testing.

I first learned I had an issue with particular foods was when my son was in the 2nd grade and I was on a field trip with his class. I ate an apple and had the worst bloating and stomach ache in the center of my stomach. An attack that I became familiar with off and on for years but didn't know why. That was 45 years ago and I am finally "getting" it. It is about certain foods. A lot of people can eat a lot of things but I cannot. I just can't.

Hi all,
I'm coming here with an update. We honestly don't know what to believe anymore. My dad took the prescribed meds for a week (that's what the doctor said), but things didn't seem to improve. They didn't necessarily get worse either. Pain / bloating is just there, not excruciating and not constant, but still there. Something strange happened last night, he had a fever (102) and severe shivers / chills. He also said the abdominal pain seemed to get worse. Because of the fever and chills (and well, the state of the world RN), this morning we decided to go to the ER. I remember reading about PC and fever / chills so of course my hypochondria kicked in immediately. We got to the ER and we told the doctor about the symptoms, we told him we've seen our GP several times and he won't refer him for an ultrasound. So the doctor in the ER decided to run blood tests and do an ultrasound. Everything came back clear. He said he couldn't see anything wrong on the ultrasound and the blood tests only showed a slight trace of infection, but nothing to worry about. Said to just take some paracetamol and ibuprofen to alleviate the pain and fever. We got home and that's what we're doing. Still, now that he got the ultrasound and nothing was there, am I crazy to still think it's extremely strange to have such prolonged abdominal pain and no explanation for it?

@cristina9532 Hi Cristina, how was the past week? Any news? Hope all is well.
