S.L.
It is very difficult to get back to normal one when thing happens after the other. This happened to me recently. I'm very healthy and never get sick. But I did get some of the nasty stuff going around and it just lead into a long, back to back illness with lots of different things going on. Well I came here asking about it and shortly after others did too. Since I have run into SEVERAL others that have reported the same EXACT symptoms appearing in the same order. Your son sounds like he has had very similar symptoms with the exception of his tonsils getting as bad as they did. But, my oldest daughter became ill around the same time I did. She had all the same symptoms with the exception of the same thing your son has gone through. Her tonsils were in bad shape and they threatened taking them. The didn't want to because of her age. She's better now. I am completely normal. One lady I met said they are about to send her to neurologist because they had run out of ideas. But it also sounds like she is at the tail end of it and coming out of it.
I think the crud people are passing around is some viruses that have mutated and are just hitting various people in various ways. It was a BAD season for sickness.
