From what Ive read ridges can be to do with several things depending on how they occur. If you have horizontal ridges its due to damage of the nail bed.

The vertical ridges are linked to ageing, but Im only 35, so I don't think mine can be attributed to that. It can also be signs of various conditions. I just wondered that due to the stress our bodies have been under due to MG if our nails reflected that stress?

Thanks for the response

Love
