Can the parasite cleanse do this?

About a year ago I did the parasite cleanse. After one day I started to get the flu symptoms, which I'm assuming were from the die off effect. It got severe enough that I discontinued after the second day.

Immediately following I had a lower back pain and TMJ that's lasted ever since.

Seems like the die off left toxins in my body that might be causeing the continued pain. 

My question is this: if I'm correct, is there a way to get rid of these toxins in a way that's mild enough to not give me flu symptoms again? I must be very sensitive since I only did the parasite cleanse for 2 days and was out for a month.

Thanks.
