I have this year's flu. Everytime I get the flu, for a week or two before I come down with the symptoms, I have my worst flare ups (nerve pain, muscle pain, dizziness (POTS), etc.). Thus, I can really tell when it is coming. I think the bad flare ups before hand might have something to do with herpes viruses getting a chance to resurface while the immune system is ignoring them and concentrating on the flu. If I double up on the Vacyclovir during this time, the flare up gets better. Strangely, once the flu symptoms start to disappear, I feel good. Really good and much better than usual! I have no idea why. It could possibly be that my immune system is tired and not doing things it is not supposed to do. I just don't know. Anyway, it is strange. I was wondering if anyone else experiences this. Does this happen to you too when you get the flu? Do you have any ideas on why it happens?
