inside anal pain after enema :(

hello...
i need some help :( i'm severely toxic wabbitte... just got my Amalgam fillings replaced, but my liver is still totally toxic and i've been getting by doing coffee enemas every few days for the past two weeks.... it's always been fairly successful with lots of chaff and even some small stones coming out of the liver... but today during the enema session, i felt some PAIN inthe anal area where u poke in the stuff (is it called catheeter?) i've always used plenty of lubricant and all, so i dont' really understand it... but it hurt -- not continuously but going in and coming out... i dont' know if this means i hurt my inside by mistake or what... and whether i should wait a long time before doing another one... :((( anyone with similar experiences?? please help.... sick and sick wabbitte... :((((
