I also have them on my thighs. I read that they are a byproduct of a clogged and or sluggish liver. I have been taking Smartcleanse and sitting in either a sauna or steam room as much as I can and that seems to be helping. Also I bought some pure cocunut oil which contains natural caprylic and rub that on...also helpful.
All the Doctors I have been to were not helpful at all. I am going to try one last time on the 20th as this new DR is supposedly something of a Candida expert. I'll see about that.
Have you considered going on Threelac? It has been extremly helpful for me. It doesn't work for everyone as it only works on certain strains of Candida, but when it does work it is extremly effective.
