The pubococcygeus (PC) muscle is part of the pelvic floor muscles that support the pelvic organs. Injury to this muscle can affect both men and women and may lead to a variety of symptoms such as pelvic pain, incontinence, or discomfort during physical activities.
A pubococcygeus muscle injury refers to damage, strain, or trauma to the pubococcygeus muscle—a key muscle in the pelvic floor. This injury can occur from physical trauma, childbirth, overuse, or other stressors. When injured, this muscle may become weak, painful, or dysfunctional, affecting bladder control, sexual function, and overall pelvic stability.
Pathophysiology of the Pubococcygeus Muscle Injury
Understanding the injury requires knowing the muscle’s structure, blood supply, nerve supply, and functions.
Structure and Anatomy
- Location: The pubococcygeus muscle is part of the pelvic floor and stretches from the pubic bone to the coccyx (tailbone). It forms a supportive sling for the pelvic organs.
- Shape and Composition: It is a thin, yet strong, band of muscle fibers. Together with other muscles of the pelvic floor, it plays an important role in supporting the bladder, uterus (in women), and rectum.
Blood Supply
- Primary Blood Vessels: The muscle receives blood through branches of the internal pudendal and inferior gluteal arteries. Good blood supply is essential for muscle strength, repair, and overall health.
- Healing Role: Adequate blood flow brings oxygen and nutrients to the injured area, which helps in the healing process.
Nerve Supply
- Innervation: The pubococcygeus muscle is supplied by the pudendal nerve along with other branches from the sacral plexus. This nerve supply allows for muscle contraction and communicates pain signals when the muscle is injured.
- Function in Sensation: Damage or injury can alter normal nerve signals, leading to pain, discomfort, or changes in sensation in the pelvic region.
Functions of the Pubococcygeus Muscle
- Pelvic Support: It supports the pelvic organs (bladder, uterus, rectum) and maintains pelvic structure.
- Urinary Control: Plays a crucial role in controlling urination by contracting and relaxing to help retain or release urine.
- Sexual Function: Contributes to sexual pleasure and function by contracting during sexual activity.
- Stabilization: Works with other pelvic muscles to stabilize the pelvis during movements and physical activities.
- Core Stability: Assists in core strength and balance by connecting the lower abdominal region with the pelvic floor.
Types of Pubococcygeus Muscle Injuries
Injuries to the pubococcygeus muscle can be classified based on severity and nature:
- Mild Strain: Small tears in the muscle fibers causing minor discomfort and temporary weakness.
- Moderate Strain: More extensive tearing, which leads to noticeable pain, possible swelling, and longer recovery time.
- Severe Injury: Major tears or trauma that may lead to significant pelvic floor dysfunction, severe pain, and require more intensive treatment.
- Chronic Injury/Overuse Injury: Repetitive strain from activities such as heavy lifting, high-impact sports, or childbirth stress that causes long-term dysfunction and weakness.
- Traumatic Injury: Direct trauma from accidents or falls that results in sudden injury to the muscle.
Common Causes of Pubococcygeus Muscle Injury
- Childbirth: Vaginal delivery can put excessive strain on the pelvic floor muscles.
- Heavy Lifting: Improper lifting techniques can stress the pelvic floor.
- High-Impact Exercise: Activities like running or jumping may strain the muscle.
- Chronic Coughing: Constant coughing can increase intra-abdominal pressure, affecting the pelvic floor.
- Trauma from Accidents: Falls, car accidents, or direct blows to the pelvis can injure the muscle.
- Pelvic Surgery: Operations in the pelvic area may inadvertently damage the muscle.
- Repetitive Strain: Overuse from activities such as long periods of standing or heavy physical work.
- Obesity: Excess weight can increase pressure on the pelvic floor muscles.
- Aging: Muscle weakness associated with aging may predispose the muscle to injury.
- Poor Posture: Prolonged poor posture can place stress on pelvic structures.
- Chronic Constipation: Straining during bowel movements can affect pelvic muscle integrity.
- Sports Injuries: Contact sports or activities with sudden movements may cause injury.
- Hormonal Changes: Hormonal fluctuations, especially during menopause, can affect muscle tone.
- Pelvic Organ Prolapse: Conditions that push against the pelvic floor can weaken the muscles.
- Inadequate Exercise: Lack of pelvic floor strengthening exercises may lead to vulnerability.
- Sexual Activity: Overactive or injurious sexual practices can stress the muscle.
- Injury from Medical Procedures: Catheterization or other interventions in the pelvic area.
- Postpartum Recovery: Not allowing enough time for the pelvic muscles to heal after childbirth.
- Pelvic Infections: Infections that lead to inflammation in the pelvic area.
- Genetic Predisposition: Some individuals may have a naturally weaker pelvic floor.

Drugs Commonly Used
While many cases of pubococcygeus muscle injury are managed with non-drug treatments, medications may be prescribed to relieve symptoms or facilitate healing. Always follow your doctor’s advice regarding medication. Common options include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) (e.g., ibuprofen, naproxen) to reduce pain and inflammation.
- Acetaminophen (Paracetamol) for mild pain relief.
- Muscle Relaxants (e.g., cyclobenzaprine) to help relieve muscle spasms.
- Topical NSAIDs applied as gels or creams for localized pain relief.
- Oral Corticosteroids for short-term inflammation control in more severe cases.
- Local Anesthetics (such as lidocaine patches) to numb pain in the affected area.
- Antispasmodic Medications to reduce involuntary muscle contractions.
- Tricyclic Antidepressants (low doses) for chronic pelvic pain management.
- Gabapentinoids (e.g., gabapentin) if nerve-related pain is suspected.
- Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) for pain modulation in chronic cases.
- Opioid Analgesics (short-term, in severe pain) used sparingly and under close supervision.
- Topical Capsaicin Cream for pain relief by reducing substance P (a pain mediator).
- Alpha-Blockers if urinary symptoms are present.
- Anticholinergics for bladder control in certain situations.
- Local Steroid Injections (if inflammation is very pronounced and not responding to oral medications).

- Laser Therapy Procedures: To rejuvenate and tighten the pelvic floor.
- Nerve Release Procedures: If nerve entrapment or damage is causing muscle dysfunction.
- Pelvic Reconstruction Surgery: In complex cases of pelvic floor dysfunction.
- Minimally Invasive Laparoscopic Surgery: To address any related internal damage while minimizing recovery time.
Preventive Measures
Preventing pubococcygeus muscle injury involves lifestyle changes, proper techniques, and regular exercises to keep the pelvic floor healthy:
- Practice Pelvic Floor Exercises (Kegels) regularly.
- Maintain a Healthy Weight to reduce pelvic pressure.
- Use Proper Lifting Techniques: Bend at the knees and keep your back straight.
