Hi, I have been dealing with entamoeba coli cyst about five days now, my doctor injected me a brownish fluid and advised me to take metronidazole 3 times a day for seven days. I am on my 5th day of taking metronidazole (flagex). I would like to ask if this is curable? Should I stop taking metronidazole after the seventh day? I am 28, 46kgs, 5 2 . Thank you so much, I really need your help.
