Just to let you know that I'm offline until Monday or Tuesday. My hand swelling has become worse and my knees and toes are now joining the party. Have just come back from a round of blood tests and will know more on Tuesday. Dori, you were right -doc is looking at Ross River as the culprit - hopefully if I have it, it's a mild case as I don't have any other symptoms.
Cheers (and as Arnie says - "I'll be back!!!")
