cmc arthroplasty

Hi
I had CMC arthroplasty on February 23rd. Yesterday I had the stitches removed and the fiberglass cast put on. I am not at all happy with the way the cast fits. I can stick two fingers down into the cast on my palm side and yet in other places it feels too tight. it doesn't feel like it's supporting my hand properly. I hate making a fuss but I'm starting to think I should speak up for myself. There doesn't seem to be anywhere near enough padding so some of the edges are very sharp. I imagine I would have the same person re doing the cast and figure I'll get the same exact result. I don't have a return appointment until the 26th of March. What should I do? Thank you in advance for any help or suggestions.

Thank you. The doctor didn't even look at the finished product. That is wrong. I've had nothing but a nightmare since I had the surgery. I just got off the phone with them and will be seen tomorrow at 3. It's really hard for me to speak up so I really hope I can say all that I need to say. Wish me luck. Thanks
