It looks like you are experiencing a major healing crisis. If you don't know what one is and how it works it can be very distressing. I know because I experienced several without knowing what they were.
I suggest reading "The Healing Crisis" and "The Detox Book", both by Bruce Fife. http://www.drlwilson.com
and http://www.arltma.com
have good articles on the topic. Also, you might want to check out the healing crisis forum on this website. I hope this helps.
