What possibly could cause the abdominal pain I've had for 4 months?

It could be Functional Abdominal Pain. I have it and it never goes away. It's there 24/7. There is no cure for it either and my pain always gets worse at night.

It could possibly be you have GERD or Acid Reflux Dieases i myself had the same or very similar symptoms could find anything wrong with me did all these tests until they said I was diagnosed with GERD or Acid Reflux Diesses. Now before you start to worry you might want to check with your Doc to see if that’s what it could be: there is a way to control it and that’s by changing your diet, staying away from all the processed foods, high fatty foods, sodas, fast food, greasy foods like fries, chips cheese burgers etc and staying away from Spicy food. You May want to check with your Doctor first

Kathy, did you ever receive a diagnosis?

I also have this pain, I've had several blood tests, ultrasounds on upper and lower abdomen and recently and endoscopy. I started off being sick with a cold around mid May and ever since I've had these chronic pains. The doc did find that my b12 levels were low but wasn't sure why, he immediately thought I was anemic or had an iron deficiency. But none were the case. Something showed up in the endoscopy how ever the doctor does this that all of this could've been caused from my stress and anxiety problems. But really who knows.

Hi Kathy,
I am so sorry you have been diagnosed with "unexplained abdominal pain", with several doctors and specialists not knowing the cause.

I do have some additional questions for you to consider (and, if you have already considered them...can you tell us more about these areas?):
1. Stress-induced symptoms can go "un-detected" on tests, but the stress in our lives can cause real physical conditions. I wanted to make sure you have considered this as a possibility, as there are numerous options and resources for you that can have sustainable impact on lessening your pain. "stress management" can be seen as "fluffy", but everyone experiences life events that are unmanageable at times, and you can experiment with removing some stressors out of your life, use this as time to reflect on any lifestyle-related changes you can make to aid in your recovery (you've heard it before, but they can truly impact your physical symptoms: physical activity, social support, nutrition and food choices, extra-curricular activities, positive outlook).
2. Have you kept a health diary, so you know specifically what is causing your pain? You can look online for "pain log" or "pain diary". The American Chronic Pain Association has a pain log that you can download as a pdf at: http://theacpa.org/painlog/painlog.aspx (it is more "cute" with images, but it might help you keep track of it better). It basically helps you keep track of your mood, stress, social support, nutrition (I would also write down what you ate), physical activity and more. Especially since you are starting a new prescription, it will help you manage your symptoms, and track possible triggers to pain (as well as what helps alleviate the pain). You did mention that the pain is worse at certain times of the day, or before/after meals. You can also focus on what you ate, what you are doing at those times of the day (or immediately before), and see what patterns emerge. You may not find the cause...but finding triggers are a good first step (after all the doctor appointments you've had!).

Have you tried (or researched) pain management techniques, including alternative medicine options such as acupuncture?
