Hi. Going by the picture it looks like a thick scar and mild edema in the suture line.
Pain and Tightness(stiffness) is due to the evolving scar tissue.
I suggest you to do mild exercises on a daily basis. Even you can visit a physiotherapist for a therapy session. Size of the scar will slowly reduce upto 10 to 30% over the months but it not disappear.

If you don't keep your wrist flexible the scar tissue will become strong and it will hamper your wrist movements.
