A sharp, stabbing pain in the rectum, colloquially termed 'lightning bum,' is more than just an uncomfortable sensation. It is a genuine medical symptom that warrants attention, according to health professionals. This peculiar pain, which feels like a sudden electric shock in the anus or perineum, is gaining discussion online after a viral video by NHS surgeon Dr Karan Rajan highlighted its potential link to serious underlying conditions, particularly those affecting women.
What Exactly Is 'Lightning Bum'?
Dr Karan Rajan, who boasts a combined following of millions on Instagram and TikTok, recently used his platform to educate the public about this strange phenomenon. In a clip from his podcast, 'Dr Karan Explores,' he discussed the symptom with gynaecological surgeon Dr Karen Tang. They described it as a sudden, sharp, lightning-type pain in the crotch or butthole that can significantly disrupt daily life.
Dr Rajan noted he has seen an increased number of patients reporting this symptom in colorectal clinics. While it might sound humorous when described, the reality for sufferers is far from funny. The pain is often brief but intense, leaving a lasting impact on a person's quality of life.
Underlying Causes: From Muscle Spasms to Endometriosis
According to the UK's National Health Service (NHS), anal pain can stem from common issues like constipation, haemorrhoids (piles), anal fissures, or abscesses. It can also indicate a sexually transmitted infection or, in rarer cases, anal cancer. However, for women, the reproductive system adds another layer of potential causes.
Dr Rajan and Dr Tang pointed to two primary explanations for this specific type of sharp pain. The first is proctalgia fugax, a condition involving sudden, severe anal pain caused by muscle spasms in the pelvic floor or rectal muscles. "Most people have never heard this term proctalgia fugax, which is this spasming of the pelvic floor or the rectal muscles, and it is a fairly common thing," explained Dr Tang. It often has no identifiable cause and can be a sporadic, though distressing, experience.
The second, and more concerning cause, is endometriosis. This is a chronic condition where tissue similar to the uterine lining grows outside the uterus. It affects more than 11% of American women aged 15 to 44, and its symptoms are notoriously painful. These include debilitating abdominal cramps, heavy periods, chronic pelvic and back pain, and pain during bowel movements or urination—which can manifest as the described 'lightning bum' sensation.
Breaking the Silence on Women's Health
A significant barrier to diagnosis and treatment is the stigma and embarrassment surrounding such intimate symptoms. Dr Tang observed that women often endure immense pain related to their reproductive health but feel too embarrassed to discuss it. "They easily get embarrassed and feel like 'oh god I'm not gonna talk about this'," she said. This silence can delay crucial medical intervention for years.
Both doctors strongly advise anyone experiencing recurrent sharp anal or pelvic pain to consult a healthcare professional. Open communication is the first step toward identifying whether the pain is a benign muscle spasm or a sign of a condition like endometriosis, which requires specific management and treatment.
