The Connection Between Ovarian Cysts and Flank Pain
It is entirely possible for ovarian cysts to cause flank pain, a type of discomfort experienced on the side of the body, between the ribs and the hip. The key reason for this is referred pain, a phenomenon where pain is felt in a part of the body that is different from its actual source. The nerves that supply the pelvic organs, including the ovaries, travel up the spinal cord and can sometimes transmit pain signals that are interpreted by the brain as originating from the back, abdomen, or flank.
Ovarian Torsion and Flank Pain
One of the most concerning causes of ovarian cysts and flank pain is ovarian torsion. This is a medical emergency that occurs when a cyst grows large enough to cause the ovary to twist around the ligaments that hold it in place. This twisting cuts off the blood supply to the ovary, causing severe, sudden-onset pain. The pain from ovarian torsion is often described as a sharp, stabbing, or cramping pain that can be felt in the lower abdomen but frequently radiates to the back and flank. Nausea and vomiting are also common symptoms associated with this condition.
Cyst Rupture as a Cause of Flank Pain
A ruptured ovarian cyst can also trigger flank pain. This happens when the fluid-filled sac bursts, releasing its contents into the abdominal cavity. The sudden release of fluid or blood can cause irritation to the abdominal lining, leading to a sharp, intense pain that can spread throughout the pelvis and lower abdomen, including the flank area. The severity of the pain depends on the size of the cyst and whether any internal bleeding has occurred.
Distinguishing Ovarian Cyst Pain from Other Conditions
Because flank pain can be a symptom of many different conditions, such as kidney stones or muscle strain, it's helpful to understand how ovarian cyst pain might differ. This is especially true for diagnosing the source of your discomfort. Below is a comparison table that highlights some key differences.
| Feature | Ovarian Cyst Pain | Kidney Stone Pain |
|---|---|---|
| Location of Pain | Often starts in the lower abdomen or pelvis on one side, but can radiate to the back and flank. | Typically begins in the back and side, just below the ribs, and moves to the lower abdomen and groin. |
| Associated Symptoms | Bloating, pressure, fullness, painful intercourse, menstrual irregularities, nausea (especially with torsion). | Severe nausea and vomiting, blood in urine, fever, chills, urinary urgency, pain with urination. |
| Pain Type | Can be dull and achy or sharp and sudden, and may come and go. Pain from torsion or rupture is often severe and acute. | Often described as one of the most severe pains possible, occurring in waves of intense spasms. |
| Triggers | Can be related to the menstrual cycle, physical activity (rupture), or no clear trigger. | No consistent triggers, though dehydration can contribute to formation. |
Recognizing Other Symptoms of Ovarian Cysts
Flank pain rarely occurs in isolation as the only symptom of an ovarian cyst. Recognizing other signs can help you and your doctor connect the dots and determine the correct course of action. Other common symptoms include:
- Bloating and fullness: A large cyst can cause pressure on surrounding organs, leading to a sensation of fullness or bloating in the abdomen.
- Pelvic pain: This is the most common symptom and can be a dull, steady ache or a sharp, intermittent pain on the side of the cyst.
- Pain during intercourse: Also known as dyspareunia, this can be a symptom when a cyst is present.
- Changes in the menstrual cycle: Some cysts can produce hormones that disrupt the menstrual cycle, causing irregular periods or abnormal bleeding.
- Feeling pressure on the bladder or rectum: A large cyst pressing on these organs can cause frequent urination or difficulty with bowel movements.
- Nausea and vomiting: These can occur, particularly with ovarian torsion.
When to Seek Medical Attention
While many ovarian cysts are benign and resolve on their own, certain symptoms require immediate medical evaluation. Seek prompt medical care if you experience:
- Sudden, severe, unilateral pelvic or flank pain.
- Pain accompanied by fever, dizziness, or rapid breathing.
- Significant abdominal swelling.
- Persistent nausea and vomiting.
These symptoms could indicate a ruptured cyst or ovarian torsion, which can be life-threatening and require emergency intervention.
Diagnosis and Management
Diagnosing an ovarian cyst typically begins with a pelvic examination and a review of your symptoms. A healthcare provider will likely use imaging techniques, most commonly a pelvic ultrasound, to confirm the presence, size, and location of the cyst. In some cases, blood tests may be ordered to check for certain markers.
For most functional cysts, which often resolve on their own, a "watchful waiting" approach is used. This involves monitoring the cyst over a few menstrual cycles to see if it disappears. If a cyst is large, causing persistent symptoms, or has suspicious features, treatment may involve medication or surgery. Laparoscopic surgery is a minimally invasive option for removing most cysts.

Conclusion
In summary, ovarian cysts can indeed cause flank pain, though it's often a symptom of referred pain rather than the primary site of discomfort. The potential for a cyst to cause ovarian torsion or rupture means that any new or severe flank pain should not be ignored. Pay attention to other symptoms like pelvic pain, bloating, and menstrual changes, and seek immediate medical help for sudden, severe pain. By understanding the connection between ovarian cysts and referred pain, women can be better advocates for their own health and ensure timely treatment when necessary.
