I started on Citalopram 10 days ago and the side effects have been not too bad up to now, the only thing is for the past I have a severe pain in my lower right abdomen, it is constant and even waking me up at night,do you think this is the Citalopram? has anyone else experienced this? I really dont want to stop them so I hope it is not them causing it. I had minor stomach pains when I started them but nothing like this. Its freaking me out a bit and causing a bit of anxiety.
