What is the cause of the stinging pain under the urine

I don't know if the stinging pain down there when urinating occurs at the same time as frequent urination or urgency. Generally speaking, stinging pain down there when urinating is caused by urinary tract infection. The pain can be mild or severe, and is usually accompanied by a certain burning sensation. Severe cases can feel like a knife cutting, while mild cases can feel like being pricked by a needle. Here are some reasons why urination hurts:

1. Cystitis

Cystitis is an inflammation that occurs in the bladder area. Most cases are caused by urethral infection that retrogrades to the bladder, so cystitis is often accompanied by chronic urethritis. When urinating, the bacteria-laden urine in the bladder stimulates the urethra, causing a noticeable burning sensation, pain during urination, lower abdominal pain at the end of urination, turbid urine, and sometimes hematuria.

When doing urine bacterial culture, it can be found that the number of bacteria per milliliter of urine exceeds 100,000. If not treated in time, it will turn into chronic cystitis, which will be protracted and difficult to cure. At this time, if you take diuretic and anti-inflammatory pills that have the effects of clearing away heat and detoxifying, and promoting diuresis and relieving stranguria for treatment, the disease can be cured quickly.

2. Sexually transmitted diseases such as gonorrhea or genital warts

If you have a history of unclean sexual behavior and then experience stinging pain when urinating, increased urethral discharge, rashes and bumps on the penis, the most likely problem is a sexually transmitted disease such as gonorrhea or genital warts.

3. Urethritis

Urethritis refers to the invasion of the urethra by bacteria, diseases/viruses and other pathogens, causing inflammation, which in turn stimulates the urethra and affects urination. It is the main cause of painful urination. When male patients are in the acute stage of urethritis, they will also have purulent secretions. A smear of the secretions or a urine bacterial culture can be done to confirm which pathogen is causing the disease.

4. Syphilis

A sexually transmitted disease caused by infection with the bacterium Treponema pallidum that can attack the heart, eyes, brain, bones, and nervous system. The disease course is very long and the symptoms appear from time to time. Its natural process is divided into three stages: in the first stage, there is no feeling, and erythema, papules, and ulcers appear at the site of virus invasion, and these symptoms may disappear after a period of time; in the second stage, the virus multiplies in large numbers in the blood, and erythema, blood rash, maculopapular rashes, etc. similar to pityriasis rosea, psoriasis, and acne appear on the skin and mucous membranes; if there is no treatment at this time, it enters the third stage, and it will be life-threatening if not treated in time.

In addition to the reasons mentioned above, there are many other reasons. It would be better to go to the hospital for a specific diagnosis.
