Thank you for your query,
Getting Typhoid fever
often is due to multi drug resistant bacteria or relapse of bacteria from the gall bladder
or incompletely treated previous typhoid fever.
Continue the medication as prescribed by your Physician for complete duration.
Take proper rest, maintain your hydration by taking plenty of oral fluids.
Eat soft food, avoid junk and fried food.
For fissure, you have to take dietary rich food, and consult a general surgeon
to assess for any surgical intervention.
Hope I have answered your query.
