I'm so sorry to hear that you are suffering so much with this stomach pain. I had my gall bladder removed about 20 years ago, and I continued to have stomach pain. I was told the same thing about giving it time. Six months later, I went to another doctor because I was in so much pain, and he said he could see the pain in my eyes. He ordered a vaginal ultrasound and they discovered a large lemon sized mass on my left ovary. They scheduled me for surgery and prepared me emotionally for ovarian cancer. Turned out that I didn't have cancer, but I did have my ovaries removed. Later the doctor discovered that my surgeon for the gall bladder surgery had left a surgery clip in my side. I occasionally have pains in that area but I'm sure it's because of the clip.
I recommend that you have your doctor look at your pancreas. You sound like you could have pancretitis, which is quite painful and dangerous if let go too long. I don't know where you live, but if possible, look for another doctor. You need to see a doctor as soon as possible as you are having acute pain. I'm not a medical professional, so I can only make recommendations for you to be seen as soon as possible. Please let us know how things turn out after you see a doctor. Best of luck for you @hgarm .
