Hello and welcome to HCM.
Thank you for your query.
Depending on the extent of injury
the healing can be predicted. The best thing for you to do as of now is to rest the finger as much as possible.
An examination by a doctor would greatly help in understanding the extent of injury, at the most the you might require painkillers and immobilization of the finger.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
