hi reikibalance,
did you took the kundalini attunement at very close interval ? in my past experience receiving too many attunement at once cause significant problem and took many month to clear.
try too find a crystal that has clearing properties. it might help reducing the energy intensity.and do grounding exercise. Kundalini reiki doesn't raise kundalini at all, it simply use a small portion of kundalini fire to help clear the spine. (so let go of any notion you are rising your kundalini). and i notice different teacher gives different quality energy attunement. so watch out for bad energy.
hope thats help
wisdom be with you
