Naturopaths call what you're experiencing a herxeimer's reaction, also called a healing crisis, which means basically that you are entering back out of the toxin tunnel (when you go it there are symptoms and when you go out, symptoms, which can be the same or vastly different than what you're used to). They tell you to welcome the experience, as it's your body working hard to recover.
I have had many such experiences doing qi gong. More colds, more fibromyalgia pain, skin eruptions, dizziness, weakness, and others. I just keep on trooping and try to rejoice that my body is healing!!
Increasing your water (esp yin yang water - pour boiling water into a cup and then add fresh spring water and if you want a bit of raw honey) intake can be very helpful. Master Lin highly recommends this.
I know this is a forum on qi gong and I don't want to get off message too much, but I've had a lot of luck when having healing crises to work on colon cleanses. The more toxic waste can be pushed out of the system the better. (Enemas, colonics, or cleanses are helpful.) Also, a bath full of 4 cups of epsom salts helps pull out toxins quicker. (According to Master Lin, don't take a hot bath right after doing qi gong; wait 30 min at least.)
