Hi,
Welcome to health care magic,
As per all these symptoms and history,you might be suffering from acute
diverticulitis.
Diverticuloum is a abnormal outward projection of mucosa of
colon.When it is get infected,it is known as diverticulitis.
You must undergo routine blood counts,ESR,
ultrasound of abdomen to diagnose the underlying cause exactly.
You can take antibiotics ( quinolones or cephalosporins) with antiprotozoals like
metronidazole,antiemetics,antispasmodics, probiotics and other supportive treatment with dietary restrictions to low fat and high protein but the main cure is the only surgical removal of diverticulam because of repeated gut infection or they could be also chances of complications like
peritonitis,bowel obstruction etc.
So,better you see gastrosurgeon and take advise.
Thanks and regards,.
