Phimosis does not always lead to symptoms. When it does, however, these may include redness, soreness, or swelling.
A tight foreskin may interfere with the normal passage of urine. In severe cases, this can prevent the person from emptying their bladder fully.
Phimosis can lead to inflammation of the penis, called balanitis, or inflammation of both the glans and the foreskin, called balanoposthitis. These conditions both tend to be caused by poor hygiene. Symptoms of balanitis include:
soreness, itchiness, and odor
redness and swelling
a buildup of thick fluid
pain when urinating
During sex, phimosis may cause pain, skin splitting, or a lack of sensation. Wearing a condom and using lubricant can make intercourse more comfortable.
