I am 26 year old female. From 1 month I was getting fever and cold again and again. 1 week ago I visited a doctor, she gave me medicines of cold, sore throat and cough and after 3 days I was feeling fine. Then I again got fever .so today I changed my doc and he advised for tests. In serology test - salmonella typhi o- positive 1: 320, salmonella typhi h- 1: 160. He has given me 7 days medicines and has suggested some injections to take. What should I do? Is this much dilution is dangerous? Please do suggest.
