Hi, French the shingles virus, is the same virus which causes chicken-pox and yes, it does lie dormant in your body, it is often reactivated by stress or illness. Someone who hasn't had chickenpox can catch it from someone with shingles, so if you have young children who haven't yet had that particular nasty, you will need to be careful when hugging them, as it's the blisters which contain the virus.
Your doc can prescribe Acyclovir tablets, starting you on a high dose, then lowering it once they start to work, which is pretty quickly.
So if your sinus infection was bad (& it sounds dire) then I'd guess (am no medic) that this might have set you off, the BSD has been developed with nutritionists & offers a sound range of foodstuffs, but as you are generally run down then I wouldn't 5:2 until feeling much better.
Elvish good luck at the Italian, if you eat meat, chicken cacciatore is on-diet!!
Good luck over Easter everyone, we live in a generally sweetie-free zone asides from 85% Dark Chocolate & cocoa nibs (from my Sirt Diet), the only real temptation is
.....so have promised DH we can have some for lunch on Sunday, or I might have a rebellion on my hands!
