Nail getting detached from skin

Hi,

I have a problem with one of my thumb toe nails. Usually, the nail is connected to the skin/flesh. But, one of my thumb toe nails is not. It started off as a very small place from the corner. I thought that the nail was shaped this way, but now, slowly with time, this is getting bigger. The nail is getting detached from the skin. Please help. I don't know why this is happening. I am not cutting off the detached part of the nail, cos it might look odd. Please help me. Will my nail ever get attached to the skin. Do I need to go to a doctor or are there are any home-remedies.

Regards,
