Have you tried A&E for an x-ray?
Quite a few people immediately asked if I'd fractured it but I'm pretty sure its soft tissue.... diclofenac has reduced the swelling a lot, seems to randomly flare up a bit, but having not used a computer since last Wednesday seems to have rested it a bit better than I managed before. Next test is back to uni for the next 2 days - see how it likes 16hrs of computing....it might be back to left handed graph making!
