Hi.
This can occur due to an acute problem in the abdomen.
The most probable causes are ;
Peritonitis meaning inflammation of the membrane covering the abdomen within inside.
There is a possibility that there is a perforation of intestine or a severe process of inflammation is going on in the lower abdomen like
enteritis.
I would advise to :
-Nothing orally
-rush to hospital
-get admitted
-investigation - blood for infection and
hemoglobin, blood sugar, liver functions ,
kidney function, serum electrolytes.
-
ultrasonography to see what the problem is like , whether there is any fluid collection, lymph node mass and to see the conditions of the internal organ
-X-ray of the abdomen in standing position.
You Need :
IV fluids and antibiotics
monitoring of vitals
Surgery if need be .
Do not try anything at home, nor be late to get admitted
