I think the pain is a Tapeworm biting harder to stay hooked. Pumpkin seeds supposedly paralyzes it, so following it up a few hours later with castor might kill it. 6 to 12 capsules frozen, or maybe just a tablespoon in a small glass of warm milk a few times --maybe it would be attracted to the milk and then killed by the castor oil. I did that protocol for 4 days once, and started the humaworm and got out a nine inch roundworm.
