Ok so I've had this "bad" thumb nail for coming up 3 years .....
It hurts. It grows, however, the nail is soft and just grows & crumbles off.
I have seen 3x Harley Street Dermatologists. All of them have tested for fungal conditions & all have come back clear.
There was no trauma to the nail, it just appeared!!
I'm fed up with it, it hurts, it looks vile & I just want to know if I will ever have a thumb nail again 
Would welcome any feedback if anyone has had anything similar or any medics, homeopath, natural medicine etc that could help! I hate it!
