1 week ago I suffered mild fever associated with nasal conjestion, head-ache, body pains, chills from second day, etc., and I took over-counter flucold tablets twice a day for three days. But symptoms are only temporarily relieving. Then consulted doctor and he conducted urine analysis and informed that I m having urine infection as seen in report 6 to 8 puscells. Prescribed me Norflox and paracetamol for 3 days. But symptoms not controlled and even I got acidity like symptoms in addition. Again consulted the same doctor and then he conducted Typhoid test and it came 1:160 positive. Then he changed the prescription to Oflox-oz and combiflam with above5 (rabeprazole) for 5 days. Right from the 1st days symptoms decreased. But today on 4th day my stool observed to be dark and tarry. Is there any problem with it ?
