Raynaud's :: Colour Change On The Lower Part Of My Fingers

so I went to my doctor since I've suffered pain since February 2012 following an injury in pe class. At the time it was put down to a not bad sprain, worsened by not using the affected wrist. I finally persuaded my mum we should do something since it hadn't cleared up after all this time. He said its raynauds, wear gloves, you'll be fine, etc etc. however, the pain has only worsened since then, the temperature of my wrist and hand has continued to decrease, the pain spreads towards my elbow/shoulder at times and I'm noticing a definite decrease in ability to use my affected wrist. It is difficult to write, open things, turn pages, and most seriously of all my daily journey on the bus is near impossible due to the pain of holding on to the bar. Is all this a consequence of primary raynaud's or is my doctor wrong?

I'm experiencing some colour change on the lower part of my fingers too, which I know is a definite sign of raynaud's.
