I though that I had varicella when I was a kid but apparently, it was not the case. And not only that, after a while I got a viral encephalitis too. Luckily, it was nothing dangerous, the doctor managed to subdue the swelling and I am ok now. But like I said, I had a lot of luck, I hope I will it have it again when it comes to health issues.
Well, sometimes the virus that causes varicella might spread to the other systems too, but it usually attacks the brain and causes the inflammation and swelling prcess starts too. That might be dangerous because some areas can be damaged permanently and that might lead to a mental retardation. You really were lucky!
