Hi Kre67a.
I'm familiar with your situation as I went thu something very similar about 4 years ago.
And if it is indeed the same, it has to do with stress induced
fungal/yeast imbalance.
What I did in my case:
I used Selsun Blue shampoo, applied, waited a few minutes and then washed my entire body with it on a daily basis for about 2 months.
I bought an antifungal cream and applied liberally on the affected areas.
I consumed daily coconut oil (antifungal properties) 4-5 Tablespoons daily-In my cooking, in my coffee, on toast etc. I still do,lol!
I abstained from alcohol-well not 100%, I enjoyed a glass of red wine with my dinner on occasion.
I meditated about 30 minutes before bedtime. I still do.
If you cannot get into a meditative state on your own, just go to YouTube and choose a meditation video clip of your liking.
Eat healthy-lots of organic greens and other vegetables,
avoid sugars and carbs and choose pastured, free range meat and poultry. Low mercury fish, some legumes and nuts
-preferably organic- are good sources of protein.
Hope this helps,
Niko
