Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. I suspect a relapse of typhoid in you. There are two reason for the relapse, either it is multi drug resistant Salmonella typhi or the bacteria is hidden on the gallbladder or bone marrow. I suggest you to do bile and bone marrow culture and sensitivity for Salmonella typhi. Once you have on hand salmonella typhi report you can take the treatment accordingly. Completed treatment can cure you completely with out causing relapse or reinfections Glad to answer your further concern contact me on bit.ly/DrArun We wish you a best health at healthcare magic. Thank you, Dr. Arun Tank If you are satisfied with my answer rate me as five star and close the answer
