teriflunomide Aubagio

Hi I a complete newbie to this forum, but I have rrms for the last 24 years, because it has been very stable for a good number of those years the last 12 have been a little more up and down. I have tried many different medications but at the moment I am in the second week of the above. I am experiencing a lot of joint pain and mouth ulcers, having read the gumf apparently this could be the side effects. Is anyone on this, have you had similar problems, how long will it last, feeling very negative about it at the moment. Where I live there is very little support, no MS nurse to talk to only the secretary of neurologist which is not a lot of help
