Hi Doctor my daughter aged 5.5 yrs is suffering from high fever since one week the typhoid and dengue tests done 2 days ago tested negative, she gets severe headache, excruciating pain in the stomach,has a rash on her chest and stomach and has also got blisters in the mouth. My doctor had adviced crocus sos and today told me to begin Zifi 100. Is this treatment fine, do we need to repeat any tests, am really worried.
