This would be very funny, if I didn't have to keep making these co-pays! smile
Ds has had his share of odd things, especially last year, it seemed like if it wasn't one thing, it was another. Lots of testing, eventually he is all fine. Part of it is he is a very very picky eater and so probably has reduced immunity when I am not just driving the fruits and veg. and vitamins.
He used to eat so much variety, relative to now.

Soup- I would ask about blood sugar issues if the doc's haven't already suggested it. I think I read somewhere if you have elevated blood sugar levels infections tend to linger longer/recur. Plus the dizzyness, exhaustion...could be something to look at. I certainly hope it's nothing major!
