No not bread, sourdough starter. They can be very old. The first one I had about 40 years ago came from Texas and the original I guess you would call it, parent, starter was over 100 years old at the time.
We used to deal with yeast infections under breasts all the time where I worked back in IL. Mostly in women who were well endowed and not wearing bras. Key is to keep underside of breasts dry and comfy. I wear front fastening sports bras and use some talc. No problems.
I believe what you are dealing with, Granny can be treated with a topical antifungal.

Make sure you wash your hands good so you don't spread it and until your doctor prescribes a treatment, keep your chaloobies-tatas-bazooms-washed gently, patted dry and you can fold some soft wash cloths and put them under your breasts if you don't wear a bra. I would recommend that you get some comfy sports bras to wear that you can fasten or pull on yourself to keep things from contacting skin under your breasts. You have a warm moist growing field there for yeast infections.
As for the labs, yes, medications can cause abnormal labs. So can simple things like age and being overweight. Our kidney function begins to decline when we are around 30 believe it or not.
