How long does it take for the pain associsted with a 1cm omental infarction to subside? is it normal to have pain 36hrs after the initial onset of sx?

Few days: Omentum itself will not give pain.As it has no sensory nerves, peritonial irritation is the cause of pain should subside in few days. Add 1 cm infraction is unusual cause of it need to be assed .1cm infraction due to torsion of blood vessel is not a plausible explanation, may be got stuck in a undetected hernial orifice look for a hernia.
