Appendicitis pain in the location of the appendix?


Hello doctor, my boyfriend and I are currently living abroad.
My boyfriend started experiencing abdominal pain and diarrhea on Thursday, October 28, 2010.
Initially, he felt discomfort and had to go to the bathroom five times in one day, but after that, his bowel movements returned to normal, and the stool color was also normal, and he no longer had diarrhea.
He did not see a doctor until the early morning of November 2, 2010, when he experienced severe cramping pain in his abdomen.
The pain came and went, and it was so intense that he couldn't sleep lying down and could only sit up to rest.
We went to see a doctor in the morning, and when the doctor palpated his appendix area, my boyfriend reported significant pain.
However, he had his appendix removed ten years ago.
Why would he feel pain in that area today? Could it be cancer?! The doctor then ordered blood tests, a breath test, an X-ray, and an ultrasound, but the ultrasound won't be available until December.
We are currently waiting for the results.
However, the efficiency of the healthcare system here in Canada is quite slow, so I am asking here to see if I can get some answers.
Thank you.

Hello Ms.
Amy: How is your boyfriend doing? I wish him a speedy recovery.
Generally speaking, acute abdominal pain can have many causes, including: 1.
Infectious causes (such as food poisoning, gastrointestinal upset, upper respiratory infections, and colds), 2.
Infections of internal organs (such as appendicitis, cholecystitis, diverticulitis, nephritis, pancreatitis, etc.), 3.
Immune system issues (such as ulcerative colitis, Crohn's disease, lupus, etc.), 4.
Intestinal obstruction, adhesions, or intra-abdominal hernias (usually related to previous surgeries), 5.
Malignant tumors (such as colorectal cancer, gastric cancer, etc.), 6.
Functional gastrointestinal disorders (such as irritable bowel syndrome, etc.).
I wonder if he has had similar symptoms in the past, and whether he has experienced fever or vomiting this time.
If so, the likelihood of infectious gastroenteritis is quite high, but we can rule out appendicitis since he has had surgery before.
As for going to the hospital for examination, blood tests and breath tests, as well as X-rays, are necessary to check for infections, inflammation, intestinal obstruction, bowel paralysis, urinary stones, liver and gallbladder stones, or gastrointestinal perforation.
An abdominal ultrasound is used to assess for any substantial lesions or tumors in the gastrointestinal and hepatobiliary systems.
Of course, if further examination is needed, arrangements for gastroscopy or colonoscopy, as well as abdominal CT scans, should be made.
I hope this information is helpful, and I wish him a swift recovery.

Understanding abdominal pain after an appendectomy can be complex, especially when the patient has a history of gastrointestinal issues. In your boyfriend's case, there are several factors to consider regarding his symptoms and the potential causes of his abdominal pain.

Firstly, it is important to note that even after an appendectomy, patients can experience pain in the abdominal area due to various reasons. The most common causes of abdominal pain post-appendectomy include:
1. Scar Tissue Formation: After any surgical procedure, including an appendectomy, scar tissue (adhesions) can form. This scar tissue can sometimes cause discomfort or pain, especially if it affects the surrounding organs or tissues.

2. Gastrointestinal Issues: Given your boyfriend's initial symptoms of diarrhea and abdominal discomfort, it is possible that he may have had a gastrointestinal infection or inflammation that is unrelated to his previous appendectomy. Conditions such as gastroenteritis, irritable bowel syndrome (IBS), or even food intolerances could lead to similar symptoms.

3. Residual Pain: Some patients experience residual pain in the area where the appendix was removed, which can be due to nerve endings that were affected during the surgery. This pain can sometimes mimic the sensation of appendicitis, even years after the surgery.

4. Other Abdominal Conditions: It is essential to consider other potential causes of abdominal pain, such as hernias, diverticulitis, or gallbladder issues. These conditions can present with similar symptoms and may require further investigation.

5. Psychological Factors: Anxiety and stress can also manifest as physical symptoms, including abdominal pain. If your boyfriend is feeling anxious about his health, this could exacerbate his discomfort.

Regarding your concern about cancer, while it is natural to worry, especially with new or unusual symptoms, it is important to remember that many other benign conditions can cause abdominal pain. The tests ordered by the doctor, including blood tests, X-rays, and ultrasound, are crucial in determining the underlying cause of his symptoms. These tests will help rule out serious conditions, including cancer, and provide a clearer picture of what might be happening.

In the meantime, it is advisable for your boyfriend to monitor his symptoms closely. If he experiences any of the following, he should seek immediate medical attention:
- Severe or worsening abdominal pain
- Fever or chills
- Persistent vomiting
- Changes in bowel habits (such as blood in stool or severe diarrhea)
- Unexplained weight loss
While waiting for the ultrasound appointment, he can also try to manage his symptoms by avoiding heavy or greasy foods, staying hydrated, and resting as much as possible. If he finds that certain foods trigger his pain, it may be helpful to keep a food diary to identify potential triggers.

In conclusion, while the pain your boyfriend is experiencing could be concerning, it is essential to await the results of the medical tests to gain a better understanding of his condition. Encourage him to stay in close contact with his healthcare provider and to follow up on any new or worsening symptoms. The medical team will be able to provide the best guidance based on the results of his tests and his overall health history.
