Hi.
Thanks for your query.
From the careful evaluation of your history; I can think of an inflammatory process going on in the left lower abdomen.
The causes can be an inflamed mass, lymph nodes or a mass or abscess of the deep muscles like psoas or so.
The best way to get a diagnosis is :
-Blood tests to determine the
hemoglobin,
WBC count for infection, blood sugar to rule out
diabetes.
-Urine test: routine, microscopy, culture and sensitivity to determine whether there is an associated
urinary tract infection as a basic cause or secondary to the problems I have enumerated.
-
Ultrasonography of the abdomen to screen for the cause and
-CT scan to confirm the diagnosis.
The treatment will start as antibiotics and anti-inflammatory medicines.
Surgery will be needed if there as an indication for diagnosis and/ or therapeutic importance.
