Toenail fungus?

[Axxtxx]

Hi, does anyone have any idea what this is? Both my big toenails fell off about 2 years ago and have grown back like this. I have clipped the edge of the nail that is no longer attached to the nail bed as it was brittle so in the picture is what’s left of the nail that’s still attached to the bed. The big nails are discoloured but the rest of my toenails are fine.

This may be a nail infection or certainly, something has damaged nail growth. To be certain of what it is a doctor needs to examine you and samples sent to be analysed
