I agree with our monkbiker friend and only add that as we open energy channels and move energy around, we often get unusual and sometimes uncomfortable sensations, feelings, etc.
All of that are good signs that we are in fact moving energy and breaking up blockages. Along with everything that MB said, I add, keep up the good work!
I.e Keep practicing! When such things happen, it is the BEST time to stay consistent in our practice, because breakthroughs are happening and more are close by. We are "three feet from gold" (see Napoleon Hill's book THINK AND GROW RICH, for more on this in a different context).
Truly, you are doing great and this is a very good sign.
