Hi Sandy

how very frustrating for your Mum and you. I had vaugue symptoms for a while, then full blown symptoms, so no I'm not in the catagory you're looking for. But be aware that symptoms can (and they vary hugely from person to person) go from not much to quite symptomatic quite quickly, well they did in my case.
I hope things don't get too bad for your Mum
take care
