It sounds like a healing crises to me with all the toxins stuck in your colon. These die offs can be horrible, I used to have so many when I did my candida cleanse! According to the candida experts group, the first thing before doing anything for candida should be a colon cleanse, so the toxins will leave the body quicker. That did resolve the problem for me, and I had no die offs at all after that. Here is a link to their post, hope it helps
