Why are there red dots forming on my skin where I have recently broken my wrist

[KMickD]

I have had a Brocken wrist for 5 months that I thought was a sprain.  It is broken right below my thumb. I had played a whole 3month basket ball with a broken wrist. After I found out that it was broken I got a cast for 3weeks, then I have been wearing a splint for 3weeks.  When I first hurt my wrist Very small red dots began to appear around wear I broke my wrist and up my arm. There are about 30 of them below my thumb and they begin to spread out as they move up my arm. I thought the red dots ment that my wrist is broken. Does this mean my wrist is still broken? If, not what do the dots mean.
