My wife has a Yeast infection and has spread to her skin. The Nystatin cream is not working fast enough as it is spreading. She had Pneumonia 3 weeks ago and they used heavy antibiotics on her and killed off all her good bacteria off in her GI tract. Now she is experiencing brain fog, blurred vision, dizziness, nausea, taste and smell is extremely changed, dry mouth, no appetite and at first diarrhea and now constipation. Her immune system is compromised. She tried taking Diflucan but severely reacted to it. What can we do about the yeast outside and inside?
