It is quite likely that these things can happen when one practices any energy exercise as one is a) gathering more energy and b) becoming more sensitive to energy. I have heard about and experienced similar things (and a whole spectrum of others as well).
These are interim effects of opening channels and clearing blockages. They are good signs of the more important results of just balancing the energy.
Glad to read your positive results and that you are moving forward to help heal yourself and others. It always makes me feel good to read these kind of posts.
Thank you.
