Discomfort in the male triangle can be caused by physiological reasons like stress and anxiety. It can also be caused by diseases such as chronic prostatitis. 1. Some men may experience pain in the area when they are nervous and anxious, not necessarily due to a real disease. 2. Chronic prostatitis can cause discomfort in the deltoid area. The main symptoms include vague pain and discomfort in the perineum and lower abdomen. Sometimes there is also some soreness in the lumbosacral, suprapubic, and inguinal areas. Treatment at this time usually involves active bed rest, fluids as well as plenty of drinking water, and some antibiotics such as ceftriaxone sodium. Once the discomfort in the deltoid region occurs, after ruling out physiological causes, go to the hospital immediately and follow the standardized treatment under the guidance of the doctor.
