This is a complicated question, and I am sorry to hear that you broke your wrist. Furthermore, I am sorry that your friend is continuing to suffer pain this far after his trauma. Perhaps it would be worth while for him to speak more about this with his doctor to see what further steps could be made to help rehab his wrist and return him to where he had been before. As for you, it is quite early in the process. You should discuss your concerns with your doctor, but in general it is entirely normal for there to be some tenderness as your body is returning to the state that it was before. The nerve fibers have been disrupted and are in the process of growing back into any areas that may have been disrupted in the process. It is not uncommon for some surgeons to suggest to patients that nerve regrowth may take up to 2 years in some cases. There are some activities and exercises that may help you to improve your function and limit pain, and an orthopedic surgeon
or a physical therapist
may be able to guide you towards these. As always, the best way to optimize your recovery is to speak to your doctor about your concerns. Please speak to your doctor.
