Too much yin?
sounds to me like you are running energy, but don't know how to channel it yet. Have you taken reiki?
I agree with hollowbone, it sound to me like your not channeling your energy. I learned this with Reiki and Polarity. You can channel in many different ways. When I was learning Polarity, I channeled my partners stomach ache. I didnt know she was having stomach problems before the session. When I was done, I felt her stomach pain. I just relaxed and let the negitive energy flow to my feet and out into the floor.
Just picture the energy in your head. White light for good energy...dark light for bad. Then when I was feeling better...I washed my hands with cold water. This disconnects the energy and washs away and bad energy that is left.
Some people have a hard time understanding or believeing this transfer of energy. I did a one time until it happen to me.
When I recieved a Polarity session, it was the most relaxing experience I ever felt! There was very little touching involved! I was suprised.
If you want , I have a chakra healing session you can perform by yourself. Even if that isnt the problem, its a great experience. I will email it to you, just let me know.
If that doesnt work, then, yes I would see a doctor. It could be early menopause. My cousin had it when she was 24!!! It can come early for her. She was a rare case, but it happens. She was lucky to have her two childeren before then.
Good luck
