Hi everyone, As always, I hope you've been well. So- I'm both newly diagnosed and a school teacher. I got started on Tecfidera approx 6 weeks ago and also am now back at school. I've only ever had optic neuritis (once in winter 2017 and made a full recovery) and I get frequent migraines (developed March 2018) and as of August 2018, I'm now on Amitriptyline at 10mg once a day and I have not had a single migraine since. Asides from that, I haven't had many symptoms. I get sporadic vertigo, pins and needles if I lean on any of my limbs for too long and a little bit clumsy when walking. Basically, nothing particularly debilitating or difficult to live with. However, since school started three weeks ago, I've noticed a few changes; in the first week, my vision began to blur, which was particularly noticeable to me when I was walking. I developed left eye pain and a left-sided headache (my ON was previously in right eye and my migraines are always right side) and so I immediately feared I was developing ON in left eye. It all went away after a few days, but now I've noticed I wake up with a slight headache a few times a week now (possibly need a stronger amitriptyline dose as body had adjusted?), but more worryingly, I've developed pins and needles that are so frequent and severe. Both my legs and arms tingle throughout the day, I feel extremely sleepy all the time despite 7-8 hours sleep a night and I feel extra forgetful. For example, I wanted to say "plum" today, but couldn't get beyond describing it was "a purple fruit that's yellow inside", much to mine and my husband's amusement. Anyway- if I get to the point, I can't stop wondering what all these symptoms mean. I guess it could be nothing and just coincidental, in that I'm back at school and my body is just trying to adjust to being busy again. But I am worried I might be headed for a relapse? Has anyone had a build-up of symptoms that eventually resulted in a relapse? Weirdly enough, I've not been finding it hard at school. I live in a new area, I'm new to the school, I teach over 300 children a week by myself, I plan all my lessons and get to school and stay in school with no difficulty every day, so I wouldn't say the stress is overwhelming, but I have always felt like I have the capacity to deal with a lot, so maybe my body and mind are on different pages about my current workload! Any advice? Since I've never had a relapse, I thought who better to turn to than my fellow MSers! I feel like my body is telling me something and I don't yet have the experience to understand and listen to it. (I sound very dramatic. FYI I teach science, not drama, by the way) Sorry if this doesn't make proper sense. Brain fog. Thanks always, Fraction
