Hi Dr. ,I have had a patch on my outer thigh that wont seem to heal, It itches at times, and when i use our Spa it seems to irritate it and also make my nipples very sensitive. Could this be a yeast infection ? I went to my doctor several times and they gave me a topical cream which seemed to help for a while but never cured it. Also my shins will start to itch after using the spa. Very frustrating, any suggestions would be very helpful.
