  • Are your strain symptoms better when you have a fever?

For me, I don’t have any eyestrain or eye muscle involvement in my LED symptoms - and an expert in BVD confirmed today after their specialized exam that I don’t have any binocular vision disorder at all (as expected for me since I don’t have correlating symptoms). I doubt that it was the 1.4 degree increase in body temperature itself that made the pressure in my head from from flicker drain away and not restart during the days with fever. The flicker sensitivity was absent throughout the 8 days that my temperature was going up and down, even in the mornings when my temperature tended to be normal. I think it’s more likely that the complex systemic inflammatory processes started by the fever (changing circulating immune protein levels and immune cell localization, etc) did something to short circuit the pressure in my head caused by flicker. I was very sick and the inflammatory processes due to the illness were very present throughout those 8 days. I guess it’s possible the slight temperature change mattered too, even if the timing of the two didn’t quite match

I’m glad heat might help for some of the people who do have eye muscle symptoms.

Liberator005 that's a very good question. Maybe new generation of monitors etc… affects our nervous system?

    Does anyone else whose LED sensitivity goes away during a fever experience unusually bad or strange symptoms when the fever ends?

    Twice in the last year I’ve had probably non-Covid viral respiratory infections with multiple days of 100-101F fever. Both times, my LED sensitivity and symptoms went away during the days of fever. Both times when the fever broke, the LED pain/pressure in my right temple came back with much greater intensity than before the fever and my LED sensitivity was greater than before the fever. Strangely, both times when the fever broke I also became scarily lightheaded with brain fog if I didn’t take steps to force extra blood to my brain - elevating my feet above my head or very actively moving so skeletal muscles would assist venous return. The first illness had been 8 days of fever and on top of everything else when the fever broke I’d get periodic brief, intense jabs of pain in the flicker spot in my right temple if I was walking around in the first couple of days (without any flicker stimulus) and the lightheadness/brain fog lasted several days. The second illness wasn’t nearly as bad as the first, had only 3 days of fever, about 40 hours of lightheadedness/brain fog after the fever broke with none of the weird extra jabs of pain.

    None of my family members who had the same illnesses experienced these weird post-fever symptoms. Since brain fog is one of my typical LED symptoms and since the extra pain was in the LED spot in my head, I’m wondering if all of this is connected - maybe inflammatory factors shift focus to the infection during the fever and then function extra-aggressively upon shifting focus back to the LED symptom spot.

    Has anyone else experienced extra-intense or strange symptoms after a fever breaks?

      I always considered migraines to be a form of inflammatory reaction. If this is or not the case, I'll let the doctors decide.

      I have migraines every day (together with light sensitivity) but the moment I have some sort of illness that requires some serious processing from my immune system (a flu, etc), the migraines are off.

      Also, if I'm taking anti-inflammatories, migraines are gone.

      The way it works with me very strongly reminds me of the "hygiene hypothesis" -- I have an immune system that just has too many soldiers without anything to do most of the time, and unless there's a real crisis needing their use, they'll pick fights here and there just to pass time.

        jen Well, I'll generally not do well after a fever (right now I'm at the tail end of a COVID week). During these periods, I'll ingest inordinate amounts of hot honey + lemon + ginger.

        I know my body to be extremely sensitive to daily fluctuations in food intake, so if I "just quit" that drink without having an intermediate period of decreasing dosage (of sugar intake, that is), I'm going to have some terrible migraines!

        If this explains what you're feeling or not, that's another question.

          __528491__ I trace to this post from your profile and boy, its strange that there are people with legitimate migraine like I do.

          The daily struggles and chores one has to deal with, the dreadfulness of waking up to a feeling of hangover etc. I hardly met anyone with a genuine struggle against migraine nowadays. Migraine is like the new Austism where people are now self-diagnosing themselves with or were misdiagnosed by a general practitioner.

          Btw, an actual Migraine has four stages. Unlike tension or sinus headache, Migraine is a neurological disorder, rather than a symptom of an underling problem. I believe you might be able to relate. While some people claimed they have a migraine attack, they also claimed they do not the light or sound sensitivity, aura or postdrome. Then theirs is not a migraine attack. One can't just skip stage 1 or 2 and exit from stage 3 (migraine attack). It is probably the other two common headache symptom.

          | The four stages of migraine |
          | --- |
          | ** |
          | Stage 1: Migraine Prodrome: includes neck stiffness, frequent yawning |
          | ** |
          | Stage 2: Migraine Aura (may happen before or while in a migraine attack):** Include visual phenomena such as seeing various shape, bright spots or flashes of light, vision loss, difficulty speaking |
          | ** |
          | Stage 3: Migraine Attack :** Pain, usually on one side, but more often on both sides-increased sensitivity to light, sound and smell or touch- pain that throbs or pulse - last between 4 to 72 hours |
          | ** |
          | Stage 4: Migraine Post-drome: Following the attack, Feeling confused and washout up to a day, or even unexplained onset happiness |
