What are your problems? I suggest you read and practice Robert Bruce's NEW Energy System if you have not. It is a safe way to develop your energy body (chi, ki) by keeping everything balanced. If you concentrate too much on a certain area and do not develop others you can become unbalanced and may experience pain such as headaches.
Oh, I was just wondering because in my first 2 years of training that sort of thing happened to me, but after a while I started to balance everything and improved on my healing techniques.
Have anybody here have had side effects when training their ki(chi,qi,etc.)? Such as increase body temp., constant head aches, etc.
Btw i have checked with a doctor, and I'm perfectly fine he says...
