Back in my college years an accident at work shattered one of my thumbnails. It grew back, sort of.
Basically, at the the tip the thumbnail tends to detach from the nailbed, become fantastically painful, and then detach even more, sometimes nearly the whole of the thumbnail.
It’s only within the past year that the thumbnail has been… normal.
I’d discovered that if I filed down a ridge that ran down the nail, then I didn’t have problems with the nail. It wouldn’t detach, it wouldn’t grow painful, and for the first time in a long time I had a normal thumbnail.
I woke up. The nail felt… funny. Like something was being stabbed beneath the nail. And upon a close examination? The end of the nail is detaching from the bed. :/
It’s going to be difficult, but I’ve got to avoid playing with the thumbnail for the next few days. Weeks, even. Don’t want to make things worse.
