Pain in the left testicle and lower stomach

Pain may travel between the lower abdomen, groin, and testicle because these areas share nerves. A hernia can cause groin pressure or a bulge that becomes more noticeable when coughing or straining. Bowel conditions such as diverticular disease, gastroenteritis, food poisoning, Crohn's disease, or coeliac disease may bring cramps with altered stools, bloating, or vomiting. Acid reflux, gastritis, and gallstones are digestive possibilities but are less typical explanations for isolated lower-left and testicular pain. Epididymal or testicular inflammation may cause swelling, warmth, urinary burning, or discharge. No single symptom identifies the cause.

Stop strenuous exercise and heavy lifting, wear supportive underwear, and observe whether the pain is sudden, constant, movement-related, or linked with urination or bowel movements. Do not press, twist, or massage the testicle. Book a prompt medical assessment for new or persistent pain; the clinician may examine the abdomen, groin, and scrotum and arrange urine tests or an ultrasound. Do not use someone else's antibiotics or delay care to see whether swelling disappears.

Attend emergency care for sudden severe testicular pain, rapid swelling, a testicle sitting higher than usual, nausea or vomiting, faintness, or a painful groin bulge that cannot be pushed back. Fever with scrotal pain, inability to pass urine, blood in stool or urine, or a hard worsening abdomen also needs urgent review. Twisting can interrupt testicular blood flow and cannot be safely assessed at home.

Tell the clinician when each pain began, whether one preceded the other, and whether you have a bulge, swelling, fever, vomiting, urinary change, bowel change, recent injury, or sexual-health concern. Ask what tests are needed and which activities or medicines to avoid.
