Hi, for the past three days I have had agonising pain in my left wrist , stretching across the back of my hand and into my thumb , just below the back of my thumb, at the base of my wrist, the vein has swollen up and is blue, depending on how i move my wrist, other veins in the back of my hand also swell up more than normal, and certainly more than the right hand. I can not weight bare with my left hand, nor move it it very much without pain, but i have not to my knowledge, injured or knocked, or in any way caused trauma to it, The pain feels like a break, even though i can move it. Can you offer advise? thanks.
