What did you do to get rid of the cyst, hb - if you did get rid of it? Was it by following the anti-yeast plan you listed below?
I started treating yeast and leaky gut in 04/06. It didn't occur to me until just this moment, that my cyst related symptoms (bleeding for 15 days each month) didn't start until this same time. I'm guessing the purging of toxins maybe kicked this into gear. Anyway, I thought the irritation from the cysts was related to yeast dieoff and continued to treat for yeast. After 6 months of repeating patterns, I realized there was something else going on and had a trans-vaginal ultrasound done. They discovered the cyst around 09/06. The doctor decided not to treat it and then I decided to research it further and decided on homemade wild yam cream for treatment. The very first month I started using the cream, my cycles shortened to 5 days instead of 15 and I no longer had the irritation that I was getting every month. Since, (the last 7 months), I've only had one day of odd spotting and I use the progesterone every day (when I remember) For a couple of months, I didn't use it during my cycle but decided for me, it might be better to continue through my cycle. As soon as the budget allows, I intend to get another ultrasound, but for now, I have to rely on my symptoms (or lack of) to tell me what's going on. During this treatment, I have also eliminated as many sources of unfermented soy from my diet as possible. Soy is reputed to mimic estrogen in the body and contribute to estrogen dominance.
If a person has yeast, it would be most prudent to treat for candida BEFORE going on progesterone therapy. Two reasons - Candida and Leaky Gut could (and very likely is) one of the primary contributing factors to hormonal imbalance AND progesterone feeds candida and could ultimately make the condition worse or cause it to cycle without forward progress.
One other thing of importance. Due to major skin itching problems, I discovered that I should stop using products containing SLS. This was my first major health related discovery. So I eliminated detergents from my home long before I treated for yeast. Later during further research, it came to my attention that SLS is a xeno estrogen (mimics estrogen) and therefore can contribute to estrogen dominance which in many cases is another major contributing factor in fibroid cyst development.
I think if I were your friend and I had fibroids, I would go for broke. Eliminate SLS first, treat for Candida next, then add progesterone therapy next. All the while attempting to eliminate as many estrogen mimics from the diet as possible - especially unfermented soy products. This is obviously not something to be accomplished overnight. From start to finish (discovery of SLS to present) has been about 15 months (or more) and it took me nearly 10 years to figure out where to even start.
