A Kundalini "Syndrome" taking place does not mean that your Kundalini is not in the process of ascent (often times the exact opposite is taking place , i.e a fast rapid ascent is occurring that overwhelms the body , what we call a "Surge").

Surges or Spikes can happen at any time during the Kundalini Phenomena , even to the most advanced practitioners .

Also awakening symptoms don't last a very long time (for some they can last years , but again they last an finite amount of time and disappear).If your awakening symptoms have disappeared it does not mean there's something the matter : it only means your body is making new energy pathways.
