I haven't gotten all the way through my Qigong program, but Master Lin has a part in the Euphoria program in which he says that in some cases, you will feel like symptoms get worse before they get much better. I think what is happening is your energy is flowing back into that area which was unhealthy and losing sensation. When the area was again enlivened, you regained sensation, and also felt the healing process occur faster than ever before. Since your body/mind recognize that healing must take place, more energy is drawn there, thus increasing your sensitivity there.
