Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. There are many reason for fever and leg pain. Without investigation you can t diagnose directly as a typhoid fever. I suggest you to do widal test, blood culture and sensitivity for salmonella. This test will diagnose your typhoid fever and gives a clue regarding possible antibiotics effective on it. For diet you should eat high protein and carbohydrate diet. Avoid spicy foods. You can take small frequent diet but avoid heavy single diet. As ulcer caused by salmonella in the intestine can be ulcerate causing many complication. Please adopt good hand washing practice as it can prevent infection to other family members. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
