Hi everyone. This is my first post. Thank you for all the support so far. I am feeling a little lost. I'm four weeks in to taking tecfidera. Hot flushes are daily but the most upsetting symptom is feeling not with it. This has got worse since the heat wa c e. Finding words. Brain fog. Having the energy to maintain concentration on a conversation. I've found it stressful. The braim tiredness has caused two episodes of slurred speech. The worst happened today with stuttering and not being able to say words correctly. I'm slow. I unexpectedly had family arrive yesterday and when they left I was exhausted and stressed. The optic neuritis symptoms of flasing and floaters started and today slurred speech at times. So I'm thinking it's stress and tiredness Is slurred speech a symptom of ms that you cope with and any advice or experience would be really appreciated. It feels really scary and like I'm making it up. When do symptoms become a relapse. Thank you
