Very sensitive nails, anyone else?

[Thinktank]

My nails have become very sensitive to touch. So much that in certain circumstances it sends shivers down my spine. They also feel and look thinner, anyone else here with the same problem?

My nails are also thinner not sensitive to touch.

Same here, and it has been so as long as I can think.
Can only cut them and even then I feel very 'uneasy'.
