Just on my way back from a walk earlier when I felt a sudden deep ache in my hand. Looked down and the knuckle's looking pretty swollen and bruised. Weird as it seemed to appear from one moment to the next without any obvious injury, and is now quite painful to move. Presumably nothing to be worried about - anyone had similar? Wouldn't normally bat an eyelid but I'm pregnant at the moment. I'm on aspirin so perhaps some unusual blood stuff going on!
