Hi, many thanks for the query!
Stop eating spicy food, avoid alcohol (if consuming) & also late night meals.
You need to do- USG (Abdo-Pelvis), X-ray KUB, Stool (Culture & Sensitivity),
RFT, CBC, Urine (Culture & Sensitivity), ECG.
Get physically examined by your doctor once.
Till then take antispasmodics, pain killers, antiemetics, diuretics, antacids like ilaprazole, sucralfate
and antibiotics as per report & with your doctor's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
Wish you a good health.
