Aussie, I have a question for you. You say that you had menengitis, but here you are mentioning the Herpes virus. Are your doctors saying that they are related? I ask this because a few years ago when I got my tonsils out, I came home from the hospital with a cold sore and now I get them frequently. I have been a migraine sufferer for 20 years. From tracking my migraines and cold sores, they are highly related. So I picked up with interest when you mentioned headache, cold sores, and menengitis all in the same breathe.
