Hi.
It looks that you are in a stage of
septicemia, in which there is an increased
WBC count and all the symptoms you have.
I think you need an admission to the hospital, intravenous fluids and antibiotics along with orally acting antibiotics on the colon, probiotics and supportive treatment as per the findings on clinical examination and investigations.
The counts to be repeated after 48 hours to see the response.
Since you had 5 attacks, I would advise to undergo further investigations to rule out any general problem like
diabetes, Cancer, HIV status and anything that can lower your immune system.
Once the current problem is over, you have to undergo
Colonoscopy,
CT scan of abdomen and other investigations as may be suspected by the clinical examination and findings
