Hi.
Thanks for your query.
Read your history and understood your problem.
Yes, you can not rally find too much material l related to
Salmonella typhi and its sequel and complications.
This is called Typhoid or
Enteric fever with its typical natural history, and can reoccur again and again if not treated properly.
This is also a type of bug.
Get the blood, urine and stool tests done again, as also
ultrasonography of the abdomen.
Typhoid can cause many complications such as:
Peritonitis and adhesion
these can cause persistent pain in abdomen again and again.
Get a 3 week course of an antibiotic,
metronidazole, probiotics, and symptomatic and supportive treatment.
I hope you will be fine if you take proper course.
