Hi
Welcome to health care magic,
I have read all your history and questions.
All these symptoms are stomach pain and indigestion could be due to
stomach upset which also might have caused your dizziness.
Stomach upset and dizziness is likely due to
gastroenteritis or
irritable bowel syndrome or
acute gastritis but here there is no need to worry as it can be cured by medications and diet.
You should go for routine blood tests and stool examination with ultrasound abdomen.
You should take antacids (
pantoprazole) available over the counter with antibiotics (ofloxacin with ornidazole) and other symptomatic treatment like digestive enzymes, prebiotics.
Avoid oily,spicy and non-veg foods for at least 3 to 5 days and must not take alcohol.
You will feel better within 3 to 5 days of this medications.
You can consult some local doctor or GP who will know about the tests and antibiotic medications.
Regards,
