So many interesting things our bodies do. I had taken the pill briefly but it does not agree with me & I can't take it. I was diagnosed with Hashimoto's disease when I was about 10 years old. Most recently I had problems with my pituitary gland not producing much cortisol & ACTH, which led me to see an endocrinologist, who is actually suspecting MS. I have my fingers crossed that it's not. I will follow you as I'm interested in hearing about your sister. Even if I don't have MS, I have become really interested in all of these diseases in the past few months.
That sounds familiar to how my sister reacts to the pill. Unfortunately it took a while longer for her symptoms to show. I have my fingers crossed for your diagnosis too.
