Hi,
Noted the history and understood the concerns.
The commonest cause of recurrent nausea, burping that tastes or smells like sulfur, vomiting in past, bloating can be due to
recurrent gastroenteritis that is not treated completely.
Hence I would advise you the following:
It is best not to get yourself treated at home.
Get the stool and blood tests done. Consult your regular Doctor for clinical evaluation, examination and correlation with reports for proper diagnosis.
This will allow a proper antibiotic,
metronidazole,
probiotic for the disease and symptomatic treatment with a PPI like
Pantoprazole,
Domperidone and as needed.
Complete the course.
Check for the source of infection like water and food.
No outside food.
Use boiled for 20 minuted and cooled water.
Take care.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
