Understanding Pudendal Nerve Entrapment

• Pudendal nerve entrapment (PNE) is a painful medical condition caused by the compression or irritation of the pudendal nerve, which supplies sensation and motor control to the pelvic floor, external genitalia, and perineum.

Aggravating Factors and Triggers

• Prolonged Sitting: Sitting for extended periods, especially on hard, narrow, or unyielding surfaces, places direct pressure on the pelvic structures and is one of the most common triggers for exacerbating pain.
• Bicycling: Riding a bicycle—particularly with improper bike seat geometry, incorrect saddle height, or lack of proper pelvic padding—puts intense, repetitive pressure directly over the pudendal canal (Alcock's canal).
• Physical Activity and Exercise: Activities involving heavy lifting, deep squatting, excessive core straining, or high-impact running can increase pelvic floor muscle tension and mechanical compression on the nerve.
• Tight Pelvic Floor Muscles: Hypertonicity, spasms, or chronic contraction of the pelvic floor muscles (such as the levator ani and obturator internus) squeeze the nerve further, intensifying symptoms.
• Postural Habits: Slouching, improper pelvic alignment, or maintaining awkward physical postures for prolonged durations.
• Bowel and Bladder Strain: Chronic constipation, straining during bowel movements, or frequent bladder urgency and pelvic straining can irritate the surrounding pelvic anatomy.
• Tight Clothing: Wearing restrictive pants, shapewear, or tight athletic gear that compresses the pelvic and hip regions.
