I am trying Methadone for ATN pain. I was on oxycontin & percocet, Lyrica, and nortryptaline. I still had breakthrough pain. I have started about 1 month ago on a small dose of methadone. From the beginning I didn’t feel right. Now I’m on 5mg twice a day +percocet for break through pain. I am feeling bad bad bad, Has anyone had this reaction? I feel depressed, anxious, shakey, pain all over my body, ( I can barely get up and stand, or bend) Is it me or is it the methadone?
