I smashed my finger while closing the car door and not have of is blue, and on the back there is a red line and it looks like an arch. I can move it and straighten it but it still kind of hurts. I don't know what to do. Should I go to a doctor? Is the nail going to fall? If the nail falls, will it grow back? Any advice? Please help me.bo
Hi,Thanks for query,
Due to injury there is blood collected under your nail and it becomes infected.
Go for antibiotic and anti inflammatory medicines,otherwise pus will be formed and nail might fall.
If nail will fall, nothing to worry,it will grow normally.
Ok and bye.
