If you don't want to try your dr. you could go to a certified naturepath and they could tell you what the problem is and what to take for it, if all of these other things fail. If could be a health related issue or just a lack of something. The naturepath I went to put me on sillica which helped. It isn't that I am against Dr.s but sometimes they don't get to the root of the problem and it's important to do that. I was misdiagonized (sp?) when I was trying to get pregnant and a chiopractor helped me. If I had taken my dr.s advice, I would still be waiting for motherhood.
