In last week of cleansing and am having horrible foot pain...

I have about 6 1/2 days left on Humaworm and Humacleanse. I am past the die-off stage and the gas, bloating, nausea, etc. have finally passed. I have always had foot pain that I could tolerate (small bone spur in each heel), but since being on HM and HC, my foot pain has become excruciating. I have done nothing else different. Could the parasite and colon cleansing somehow be causing the increased pain and if so, why? I can barely walk and am in horrible pain.
