What is lightning crotch?

Lightning crotch is a sudden, sharp pain in your vagina, rectum, or pelvis that many mamas feel towards the end of their pregnancy. Most women report that it increases in frequency and intensity as their due date nears. This is due to the increase in pressure from your growing baby!

Lightning crotch often comes on without any warning and is normally short-lived. Episodes occur in quick, painful bursts. While some people might mistake it for other pregnancy-related ailments, lightning crotch is actually its own thing. 

Round ligament pain and sciatic nerve pain are other uncomfortable sensations you may feel in the pelvic area…but neither are quite the same as lightening crotch.

Symptoms of lightning crotch: What does lightning crotch feel like?

Most describe it feeling like an electrical shock or a feeling similar to when you hit your funny bone. It’s crazy, but when it happens it can definitely take your breath away. Are you nodding your head in agreement right now? Ha.

Generally, the sensation doesn’t last longer than 15-60 seconds. And the intensity of the symptoms can vary from person to person and even from day to day. 

There’s no clear reason why lightning crotch occurs, but many believe it is due to the increasing pressure that baby’s head is putting on surrounding things in the pelvis. And the good news is that it’s no cause for concern – just another one of those unexpected things you get to experience during pregnancy.

Hospital Bag Checklist-1

What causes lightning crotch?

As I mentioned previously, the cause of lightning crotch is not well understood, but it is thought to be related to baby’s head putting pressure on your cervix, vagina, and pelvis. As baby moves, the nerve that runs to the cervix can be aggravated, causing sharp pain. 

Some hypothesize that it’s also related to baby dropping lower into the pelvis as you get closer to your due date. This would make sense, as most women experience lightning crotch in the last few weeks leading up to their due date. 

When does lightning crotch usually happen?

Lightening crotch is most common in the last 4-6 weeks of pregnancy. It’s not uncommon for baby to drop lower into the pelvis as you get closer to your due date. 

Sometimes when this happens, women notice certain pregnancy-related symptoms become more intense or more frequent with lightning crotch being one of them. Others include things like low back pain, sciatica pain, the urge to use the bathroom, urinary incontinence, and more.

How can you get relief from lightning crotch?

Unfortunately, there’s no way to completely prevent lightning crotch from occurring but there are some things that might bring you some relief!

  • Belly support band: A belly band can help relieve some of the pressure on the pelvis 
  • Change positions: Simply changing positions might be enough to get baby to move and relieve pressure from whatever they are pushing up against
  • Swimming: Swimming is such a wonderful way to experience a feeling of weightlessness during pregnancy! Not only can it prevent lightning crotch, but you’ll also experience relief from swollen joints, an aching back, and more
  • Prenatal massage: Similarly, massage can help bring relief to lightning crotch and many other late pregnancy discomforts
  • Warm bath: And again, this is not only good for lightning crotch but can also relieve other pregnancy-related aches and pains. Are you sensing a theme here? 🙂

Should I call my provider if I experience lightning crotch?

Generally speaking, lightning crotch is a normal part of pregnancy and is nothing to be concerned about, especially if it resolves quickly and isn’t happening all the time. 

Lightning crotch alone normally doesn’t warrant a call to your OB provider but if you are experiencing lightning crotch accompanied by any of the following symptoms, definitely let your provider know:

  • Vaginal bleeding
  • Cramping and/or contractions
  • Significant pelvic pressure
  • Pain that doesn’t resolve 
  • Severe pain
  • Decreased or unusual fetal movement
