Matth3w,
It sounds like the orthopedic surgeon basically told you what happened to your hand. You have had the "million dollar" work-up: x-rays, MRI, CT scan, and dynamic stress testing under fluoroscopy. It appears that when the hockey stick hit your hand you sustained both a direct blow (resulting in a deep contusion) and a subluxation of the CMCJ. The ligament tore a little, the bone moved a little out of place, then snapped back into place. Now the ligament has healed, so the surgeon can no longer push the bone out of place.
The fact that the antiinflammatory medicines are helping is a good sign.
But, you have had a significant injury to your hand. It may feel better, and it may actually get better with time, if you are lucky. But, it also may never actually feel "normal", whatever that is. If you have developed some scar tissues around the area, it will not stretch like regular tissues, so it may always feel a little tight. But, then again, with time, the scar tissue may mature and stretch out. Who knows. (It takes about a year for significant scar tissue to mature and stretch out.)
But, the good thing is that the bones are located in the proper place and you do not need surgery to fix anything. Hands that have to be operated on usually get better, but always have scars and sometimes chronic pain.
You may just have to learn to live with the "feeling" that you have in the hand. If it really bothers you, you might ask to see the occupational therapist (hand therapist) and they can do some inotophoresis, ultrasound, or friction massage on the spot that bothers you.
But, if it is deep scar, that may just be part of you from now on.
Hope your hand "feels" better. Try not to get hit again when you are playing hockey. If you are going to play, tape that hand up really well. Good luck.
