I've been taking amitryptaline for a while now and originally was prescribed it to help to slow my digestion down and thus help the diarrhoe. It seems that since I've been taking amitryptaline I've started to get a dull ache in my gut most days and nights. I thought there were studies that said that tricyclics were known to help with pain (rather than help diarrhoea which is what I am taking it for). So why would I be getting pain when I didn't used to get it before? Anyone else had this with taking Ami?
