As I said in a previous blog article, my MS symptoms are visual: blurry vision and double vision were my main symptoms during my last flare. These last three weeks have been up and down in terms of MS symptoms. I have had some blurry vision, on and off. It is not as acute as during my last flare, but definitely present.
The Biogen nurse told me, the symptoms could be happening because of the temperature going up and down lately. I don't seem to find an obvious correlation between outside temperature and my MS symptoms and I do seem more sensitive to exercise intensity. Thursday, my running training involved a 2km warm-up and an easy pace, followed by a tempo run consisting of: 2km on a slight uphill, then up long stairs (260 steps), running two by two, and a slight uphill of about 1km. After the first kilometer of the tempo (tempo means speed I can say two short words in, no more and no less), I started having blurred vision. That was even before I hit the stairs. When running up the stairs, intensity went up and blurred vision accentuated. All that to say, it's not the first time I run tempo runs, I do so almost every week. But it seemed that it's getting worse.
This could be related to the fact that my blurred vision increased overall. When I started Tecfidera, I thought it was improving. And although, the Tecfidera literature did not mention any improvement in symptoms, I thought it might help some. But now, I'm back to the same or worse. We're in August, one month left until temperatures start going down. We'll see if this blurriness tapers off.
