Can dyspareunia cause pain radiating to thighs?
Yes, deep dyspareunia can sometimes cause pain that radiates to the thighs, buttocks, or lower back, due to nerve involvement or pelvic muscle referral.
Detailed Medical Explanation
Pain radiating to the thighs may result from irritation or inflammation of the pelvic nerves or muscles, particularly in women with deep endometriosis, pelvic inflammatory disease, or muscle spasm. Referral pain patterns are well recognised in pelvic pain syndromes. NHS: Painful Sex.
Clinical Context
If pain spreads to thighs or lower back during or after sex, medical review is important to rule out nerve or pelvic floor involvement and guide management.
Evidence-Based Approaches
NICE and RCOG recommend assessment of referred pain patterns and multidisciplinary care for complex dyspareunia. RCOG: Dyspareunia.
