Hi.
Thanks for your query.
Read the history and understood it.
To recapitulate:
Your husband has -
severe pain - occasional swelling in left lower abdomen - radiates to the back - chills, sweats and fatigue.
All these symptoms are suggestive of a 'close -cavity infection in the abdomen.
The probable causes can be :
-
Pyelonephritis.
-Severe colitis with an active infection.
I would advise you the following:
nvestigations:
*Routine blood investigations like Complete blood picture, blood sugar, urea, creatinine, liver function tests,
thyroid function tests.
*Urine -routine and microscopy, culture and sensitivity.
*Stool: routine, microscopy, occult blood, culture and sensitivity.
*
Ultrasonography of abdomen,
All these investigations along with a physical examination by a
General Surgeon would help you to get an exact diagnosis and a plan for a perfect treatment.
