Ridges and more ridges

Vertical ridges are hereditary.  Think of them like wrinkles in your nails - the older you get, the more you will see them.  This doesnt mean you have to be old to get them, though - I have seen them in very young clients!  And I have seen old clients with none.  Is in your genes.  If they arent too deep, you can take a light buffer and smooth them out and use a ridge filling base coat.  If they are deep, you can still smooth them a bit, but dont try and buff them out all the way or else you will weaken your nails!

Nope, there is so little calcium in your nails that it makes very little difference if you have a deficiency or not!

Horizontal ridges are generally caused by some type of damage.  1.  A severe illness can cause your nails to stop growing temporarily and usually shows up a few months later.  2.  Since you say they are mostly on your thumbs, I am suspecting a habit tic.  Do you pick at your cuticles?  Constant cuticle picking causes damage to the nail matrix which will show up as horizontal lines.  If you stop, you may - or may not - reverse the damage.  It depends on how much damage was caused.  3.  Obvious damage such as slamming your finger in a door.  Sometimes this type of trauma can cause permanent damage which will grow out as a ridge continuously. 4.  The last thing I can think of is overfiling the top of the nail or buffing it at a wrong angle.  The file will cut into the nail causing a ridge.

If it was on all nails then maybe, but you said your doc says you are healthy, so it is probably permanent damage from a really long time ago.
