There are more and more male clinics, and many of them have a dull pain in their left abdomen. I would like to remind men that there are many reasons for dull pain in the left abdomen, such as prostatitis, varicocele, left ureteritis, left ureteral calculi, acute pancreatitis, etc., and the pain in the left abdomen caused by each reason is unbearable for men. So what? Let's ask a well-known expert from Beijing Men's Hospital to analyze: Acute pancreatitis can also cause pain in the left abdomen of men: the common symptoms are severe and persistent pain in the upper abdomen or left upper abdomen (sometimes the pain extends to the back), nausea and vomiting, fever, and the pain will be slightly relieved when leaning forward. Experts said that in fact, these are only secondary causes of male left abdominal pain, mainly prostatitis. Prostatitis, the clinical manifestation of prostatitis is that the perineum or suprapubic region is under heavy pressure, which is aggravated when sitting for a long time or defecating, and spreads to the waist, abdomen, back and thighs. Left varicocele varicocele mostly occurs on the left side, and its incidence rate accounts for 10% ~ 15% of male patients with left lower abdominal pain, and it mostly occurs on the left side. The characteristics of male left lower abdominal pain are more obvious when sitting, and the pain radiates to the left perineum and may be accompanied by testicular pain. This is a common problem among young people. The vein in the spermatic cord is blocked for some reason, and the blood stagnates, which makes the tendril vein plexus in the spermatic cord meander, lengthen and expand, and forms an earthworm-like mass in the scrotum, which is called varicocele. When varicocele occurs, the scrotum is swollen, heavy and heavy, which is aggravated when standing, walking and working, and relieved after lying down and resting. Left ureteritis and left ureteral calculi can also cause pain in the left lower abdomen of men. Left lower abdominal pain is often accompanied by pain near the left lumbar vertebra or left waist pain, paroxysmal colic and hematuria under microscope, and tenderness of the left ureter. ?
