Ms. Lisa Hooks,
It seems to be GASTRO-COLIC
REFLEX due to Stress
But still get yourself checked for Complete Blood Count
, Urine (Routine & Micro), Stool (Routine & Micro) and S. Widal. There should be two reports of S. Widal two days apart.
Meanwhile you may take
PROBIOTICS with B-COMPLEX (Tab. FOLISPOR twice a day with food)
a PROTON PUMP
INHIBITOR (Tab. ACIBAN-40 on empty stomach once day 1 hour before breakfast).
