I was diagnosed with candidas or thrush about two weeks ago , have not felt well for three weeks now, headache,nausea,heartburn,diarrhea,fatigue,bodyaches my stomache is tender and rumbling all the time. Doctor has prescribed Nystatin and Diflucan (4-150mg ) I am also taking zantac and imodium. I have really been watching what I eat . I am scared of taking this medicine after reading the side effects. My throat is still tender all red and white. Should I go to a specialist in this field? ?
