I feel the same thing in my legs. Like they are about to snap at any moment, especially when I have to walk downstairs or uphill. I am currently doing colon cleansing with bentonite, starting to feel a bit of relief, but only on my first week now.
In my case right now it's the damage from all the parasite toxins that I have to deal with.

Sosick, I am curious about hydrotherapy. Have you tried it? Is this something a weak person can handle when I am feeling so sick and malnurished? Is it hard on the body to do, or would I just feel better from it? I am considering doing it after I finish my parasite cleanse to get all the crap out of my intenstines.
