Hello!
Actually, when you have joint pain, you tend to be a bit more Th1 dominant. When you kill off parasites, you signal more TH1 immjne cells to be produced triggering a bit more dominance and therefore joint pain.

The other cause of joint pain during a cleanse is that you dont have enough liver support so as parasites die off, they release toxins and heavy metals into the blood. If your liver and kidneys cant eliminate those toxins, they will be deposited into tissues. If your body leaves those toxins in the blood, they can pass through your vital organs (heart) and cause damage so your body redeposits them into tissues to get them out of the blood. Heavy metals released from parasites usually get deposited into joints, hence joint pain. This surge of toxins without anywhere to go causes inflammation and more pain. I always suggest doing liver drainage WHILE on a cleanse. You can find my suggested liver and kidney drainage protocol under the RESOURCES TAB.
HOPE THIS HELPS 🙂
