Painful or difficult urination
Bladder problems. In some cases, the sores associated with genital herpes can cause inflammation around the tube that delivers urine from your bladder to the outside world (urethra). The swelling can close the urethra for several days, requiring the insertion of a catheter to drain your bladder.
Pressure in the lower stomach
An infection in the urethra which affects the bladder as well leads to a feeling of pressure in the area below the stomach. The pressure and pain increase when there is an external body touching the lower abdomen.
