Will my nail grow back ?

so around the 10th December i pulled a hangnail which then got infected and caused my nail to detach from the nail bed end, its been over a month and i cant see any sign of a new nail growing, i know nails can take a long time to grow but i thought i might have seen some sign of a new nail by now :/ i had to cut the dead white part of the nail as it was catching on everything and the skin under the nail is very hard do you think it will grow back ? is there any point in going to see my doctor ? thanks

It’s growing, but it probably damaged it way back below the cuticle. So it could take a few months just to be able to see the new part.
