After undergoing an appendectomy, many patients expect relief from the painful symptoms of appendicitis. However, an unexpected discomfort can arise—shoulder pain. While it may seem unrelated to abdominal surgery, this common post-operative symptom can leave many wondering why their shoulder hurts. If you’ve recently had your appendix removed and are dealing with this puzzling pain, you're not alone. Here’s a closer look at what might be causing the pain and how you can find some much-needed relief.
Appendectomy is one of the most commonly performed surgical procedures. While the open method was once the standard treatment for acute appendicitis, laparoscopic appendectomy has gained significant popularity in recent years.
In laparoscopic surgery, creating a pneumoperitoneum is a crucial step, allowing the surgeon to view and access internal organs through small incisions. This process involves introducing gas, typically carbon dioxide (CO2), into the abdominal cavity to create space for the surgeon to work without interference from surrounding organs. Pneumoperitoneum helps the surgeon see and access organs more easily, allows for smaller incisions, reduces pain and scarring, and ensures stable pressure, minimizing complications.
Despite the advantages of laparoscopic surgery, many patients report experiencing shoulder or subcostal pain after the procedure. This can be puzzling, as the pain seems unrelated to the surgical site. The main cause of this discomfort is referred pain, which occurs when the body perceives pain in an area other than where the injury or irritation actually occurs.
For a clearer understanding of the connection between laparoscopic surgery and shoulder pain, check out this Instagram reel by Dr. Hunter Norton, a Urology PGY-1 resident, (@nort_fam). In the video, Dr. Norton explains the mechanism behind referred pain after surgery and the role of the diaphragm in causing post-operative discomfort.
For most patients, shoulder pain lasts only a few days and usually subsides as the CO2 gas is absorbed and the irritation to the diaphragm decreases. However, in some cases, the pain may persist for up to a week or more, depending on individual factors such as the amount of CO2 used, the duration of the procedure, and the patient’s sensitivity to the irritation.
While shoulder pain is common after laparoscopic appendectomy, it is usually mild and temporary. There are several ways to manage this discomfort:
Over-the-counter pain relievers such as ibuprofen or acetaminophen can help reduce pain and inflammation, unless advised otherwise by your doctor.
Applying heat or cold to the shoulder can provide relief, with heat helping to relax muscles and cold numbing the area, after the first few days.
Gentle movement or light stretching, as advised by a healthcare provider, can help relieve muscle tightness.
Positioning during rest can help prevent further irritation, such as using pillows to support the body in a comfortable position.
While shoulder pain is usually harmless, it’s important to seek medical advice if:
The pain becomes severe or doesn’t improve within a few days.
There are additional symptoms, such as difficulty breathing, chest pain, or fever.
Signs of infection appear at the surgical site, including redness, swelling, or discharge.
Shoulder pain after an appendectomy might feel unsettling, but it’s generally temporary and part of the healing process. Most of the time, it will go away on its own within a few days. If it persists or you experience other concerning symptoms, it is advisable to contact your doctor. Rest easy knowing this discomfort is usually nothing to worry about!
