Sometimes after urinating, I experience a sudden pain for a few seconds when I contract my pelvic floor muscles.
This happens occasionally.
What could be the cause? Thank you!

Hello: Pain during urination may initially suggest the possibility of urethritis, but since you mentioned it occurs occasionally, I recommend that if you experience discomfort, you should visit a nearby medical facility for evaluation.
A urine test is necessary, and the physician will need to perform a physical examination and take a detailed medical history to make an accurate diagnosis.

More Info


Experiencing sudden pain after urination can be concerning and may arise from various underlying causes. While it is not uncommon for individuals to experience transient discomfort after urination, especially if it occurs infrequently, understanding the potential reasons behind this symptom is essential for appropriate management and reassurance.

One possible cause of the pain you describe could be related to the urinary tract itself. Conditions such as urinary tract infections (UTIs) can lead to discomfort during and after urination. UTIs often present with symptoms like a burning sensation, urgency, and frequency of urination, but they can also manifest as sudden pain after urination. If you have had a recent UTI or have experienced similar symptoms in the past, it may be worth considering this possibility.

Another potential cause could be related to the prostate in men. Prostatitis, which is inflammation of the prostate gland, can lead to pain during or after urination. This condition can be acute or chronic and may present with additional symptoms such as pelvic pain, difficulty urinating, or discomfort in the lower abdomen or back. If you are male and have experienced other symptoms associated with prostate issues, it may be prudent to consult a healthcare provider for further evaluation.

Additionally, the sensation of pain after urination could be linked to pelvic floor dysfunction. The pelvic floor muscles play a crucial role in urinary control, and if these muscles are tense or overactive, they can cause discomfort during or after urination. This is particularly relevant if you have a history of pelvic floor issues or have engaged in activities that may strain these muscles.

Nerve-related issues could also be a contributing factor. Conditions such as pudendal neuralgia, which involves irritation or damage to the pudendal nerve, can lead to pain in the pelvic region, including after urination. This type of pain may be described as sharp, shooting, or electric-like and can be exacerbated by certain positions or activities.

In some cases, the pain may be related to anatomical factors, such as urethral strictures or bladder stones. These conditions can cause obstruction or irritation during urination, leading to discomfort afterward. If you have a history of urinary tract issues or have undergone procedures involving the urinary system, these factors should be considered.

It is essential to keep track of any additional symptoms you may experience, such as changes in urinary frequency, urgency, or the presence of blood in the urine. If the pain persists, worsens, or is accompanied by other concerning symptoms, it is crucial to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, urinalysis, and imaging studies if necessary, to determine the underlying cause of your symptoms.

In summary, sudden pain after urination can arise from various causes, including urinary tract infections, prostate issues, pelvic floor dysfunction, nerve-related conditions, or anatomical abnormalities. While occasional discomfort may not be a cause for alarm, persistent or severe pain warrants further investigation to ensure proper diagnosis and treatment. Always consult with a healthcare professional if you have concerns about your symptoms or if they significantly impact your quality of life.
