Hi all. I just came back from sydney i had an ERCP and a sphincterotomy. Its to try and help my digestive system which is in TERRIBLE shape and is 'the' root cause of my FM/CFS. Anyway, i had it done, they cut the sphincter music open inside at the base of my bile and pancreatic duct. I had an attack of pancreatitis the next night that required 75mg of pethadine injected - was so bad. The night after that i was getting better and they tried me on a low dose of methadone for pain. OH MY GOOOOOSH! i had whats called a dysphoric reaction. After about 2hrs on it my body started getting heavier and heavier. felt like a fridge was lying on top of me, could hardly move. i started feeling irritable then that got worse and worse until i felt like i was actually going insane with hundereds of voices and thoughts coming at me at once, it was like being in hell, and it lasted all night with no sleep. I wanted to call someone but i couldnt, i wanted to get up to tell some1 but couldnt move, it was torture. It effected me for 5 days after too, and every day my BP was sooo low etc - felt like i had been on cortisone and suddenly stopped - soooooooo dam weak it was so scary. Could barely get out of bed for 5 days. Im even feeling the effects of it still over a week later. I will never ever touch that crap in my life again. Anyway, big ordeals like that always knock me down for so long, because it takes me aaaages to get over it, to heal, and to get a fraction of energy back that i didnt really have in the 1st place. *sigh* I hope it starts picking up soon. Im about to start elavil but waiting till my BP isnt so unsteady cause it can lower it. Does anyone take elavil who also already has low blood pressure? im hoping it helps me with autonomic dysfunction and pain. Chris.
