Hello Doctor. I have just finished my antibiotics treatment for typhoid fever as prescribed by my doctor. I felt well a few days after, and then some symyoms came back. The headaches (very frequent) and stomach upset. Also, I noticed that my eyes become tired easily and feels strained when I use my smartphone. My anus is itchy and I have a mild sorethroat (not painful). I m going back for a check up with my doctor tomorrow. Please, help me to understand what could be wrong? Thank you as your reply would be very appreciated.
