Give it some more time -- three weeks is not enough for the bone to heal.
Hi and welcome to the Spinal Cord C/D forum.
I have to agree with philnoir....give it more time....not only for the bone, but the nerves themselves may not have damage but will still need to heal.
5 yrs ago I had surgery to help with some neuro issues and was told nerves can take up to 2 yrs to heal completely...some of us it may not be as long or can take longer....
Unless you have new symptoms or sensations, I would wait before you contact the Dr.
Good luck and keep us posted on your progress : )
