Hello. I am a 40 yr old female. I am prone to yeast infections. I have been battling either a vaginal yeast infection or an external itching off and on since July. My GP has prescribed the Diflucan Pill (2x in July and 2x recently). She also prescribed an external cream that helped temporarily. I am now experiencing itching all over my body but especially under my arms and scalp. Could I have a yeast infection that is through out my body? When I go to my doctor, what test should I ask for and what are some other treatments that could be tried. This itching is affecting me emotionally, mentally, and I am tired more often. My husband is not too happy about it either. I do not have HIV or sn STD.
