Sensação de Cosquicho no Abdômen Inferior: Diagnóstico Diferencial e Quando Procurar Cuidados

A tickling/pulsatile sensation in the lower abdomen is atypical and warrants evaluation.

Potential Causes

• Gas/peristalsis: Normal intestinal movement; often with bloating, flatus.
• Muscle fasciculations: Rectus abdominis, obliques — fatigue, electrolyte imbalance, stress.
• Nerve irritation: Ilioinguinal/iliohypogastric/genitofemoral neuralgia (post-surgical, entrapment).
• Vascular: Abdominal aortic aneurysm (AAA) — pulsatile mass, thrill; emergency if expanding/ruptured. Mesenteric ischemia.
• Gynecologic: Ovarian cyst, endometriosis, fetal movement (if pregnant).
• Urologic: Ureteral stone (colic), bladder spasms.

Red Flags

• Sudden severe pain, hypotension, syncope (AAA rupture).
• Fever, hematuria, weight loss.
• Neurologic deficits (saddle anesthesia, bowel/bladder change).

Evaluation

History, abdominal exam (pulsatile mass?), CBC, UA, ultrasound/CT aorta, pelvic ultrasound if female.

Do not self-diagnose; vascular and neurologic causes require urgent exclusion.
