I have found that a free BM takes care of that pressure - I have a different kind of parasite Neurocystoricosis - tapeworm. If you drink two tablespoons of epsomsalt disolved in water with a solid regimen of citrus fluids, I favor a mix of frozen juices - two orange, one grapefruit, and plenty of fresh squeezed lemon, you will relieve some of that pressure. This equals about 3 pitchers and an early start in the day that you must be in close proximity to the john. I watch racing. This stimulates the limph nodes - you feel warm and aggravated but the next day you feel great.
