Carpal Tunnel Syndrome Question

I had bilateral carpal tunnel release surgery in May (left non dominant) and July 2018 (right dominant). Since surgery, my right fingers have been extremely swollen. For example: on the morning I cannot straighten my fingers from swelling and my fingers turn white. I can say that I am able to move my fingers after a short time but the swelling seems to remain consistently; to varying degrees. Left hand isn’t nearly as bad, but the elbow is where my issues are with that area. I’d like to address the right hand issues first. And, can I ask about the elbow here, as it can relate to carpal tunnel".
