Sorry if this has been posted before - I did check, but other toe nail questions seem slightly different.
Both of my large to nails keep snapping about half way down. This is the same as when you are growing your finger nails and they start to snap, except this is only about 1/2 to 1/3 of the way up my nail (horizontaly breaking).
My big toes feel a bit sore too - sort of like it feels when you bend your nail back.
Feel a bit silly going to the docs with this, so would be grateful for advice.
