our livers and kidneys filter all toxins from our bodies,,,from food,,,body takes nitrigen and converts it to amonia,then passes it to our kidneys,,to .pee out,,,but,,if kidneys and or liver arnt working very well,,we retain the ammonia in our blood stream,,,which is nuro toxin,,it then crosses the blood brain barrier,and acumilates in our brain,,and can and does iritate nerve function,,and signaling,,the quantities of of ammonia will dictate the ammount of pain we have,and its duration,and this will be goverend by how much proteine we have eaten,,
