Dear Mam,
I really don't understand the till now why haven't you consulted a doctor.
You should not do self prescriptions in your case.
I understand that every time it is not possible to take
medical help. But i am saying this specially for you because you are a diabetic.
In diabetic patients , infections can precipitate a serious complication called as Diabetic
Ketoacidosis.
Your
metallic taste is most probably because of the
metronidazole antibiotic you are taking.
Salmonella infections presents in many forms, typhoid, dysentry. We need to know the exact symptoms to tell you what antibiotic you need and for how many days.
Since you are a diabetic, mam please consult a doctor. You are loosing weight,
severe dehydration can even lead to your kidney involvement, as being a diabetic your kidneys are in stress.
Get your tests done, get properly treated, Stay Healthy
