My niece came to school in Jinan and suddenly called me early in the morning, saying that she had stomach pain, back pain and fever. Because half a month ago in my hometown was diagnosed with appendicitis, although I took medicine to get better, but the new students after the military training, the heat mosquito bites and other factors, I have been worried about her appendicitis attack up, received a phone call is also very nervous, no matter how, a long way to cast to come, before the start of classes to do a surgery is not really what I look forward to. I rushed to the hospital and looked for the surgery department to check the body, abdominal pain, no stomach pain, nausea and vomiting and other gastrointestinal reactions, bilateral lower abdominal pressure pain, heavy on the right side, pressure pain at the Mai’s point, pain behind the right hip, and limited walking. The surgical opinion still considered appendicitis because of the pain in the whole abdomen and the fear of a strong appendiceal edema or abscess occurrence, so immediate surgery was recommended. However, careful ultrasound examination did not show any thickening or edema of the appendix, no edema in the iliac fossa, no signs of ovarian cysts, no increase in leukocytes or granulocytes in blood tests, and no painful manifestations like ureteral stones. Although it is not good to say that chronic appendicitis can be completely ruled out, several acute abdominal conditions are atypical, and as a pain physician, I always feel less like When the gynecological surgery and various examinations were done, I started to implement the pain examination, and the result was obvious pressure pain (++) in the L3 transverse process bilaterally. When I got up from the treatment bed, the pain in my back and hip had been relieved and I was laughing and talking with my classmates. When I saw all this, my heart began to drop. I felt much more relaxed because I could avoid surgery. After an hour or so, the right lower abdominal pain disappeared and the left lower abdominal pain was only a slight pressure; after another half hour, the left lower abdominal pain also disappeared, but my body felt weak and powerless. After lunch, he returned to school accompanied by his classmates and was instructed to observe closely and contact them as soon as there was any situation. From the above analysis, the L3 transverse process block was not sufficient to block the innervated nerves innervating the appendix or ovary, so the possibility of masking the pain symptoms due to diagnostic treatment could be excluded. In our experience in the pain department, we have often seen patients with long-term persistent abdominal pain (especially lower abdominal pain), basically mainly women, with onset time ranging from half a year to many years, pain with or without activity, some getting better with activity, some getting worse with activity, related to menstruation or not, most treated with adnexitis or pelvic inflammatory disease, and some having had gynecological surgery; some with only lower abdominal pain, some Some also have lower back pain, posterior hip or posterior thigh pain, and in severe cases, nausea. The common feature was that there were no obvious positive findings in the ancillary tests (imaging, blood), and the only positive finding was a positive physical examination for L3 transverse process pressure pain. Diagnostic treatment of L3 transverse process intervention can reduce or eliminate the symptoms, i.e., the diagnosis is clear, and it also plays a good therapeutic role, and the majority of patients’ pain disappears after 1-2 treatments. However, this is the first time that an acute attack like the above case has occurred. Again, we remind you that when you have the above symptoms, you should pay attention to identify the presence of L3 transverse process syndrome after excluding various common causes of abdominal pain or when common causes cannot be explained or treatment is ineffective.
