My fingernails have been a disaster for months and months.
The Gem/Tax chemo last summer made them really thick, with ridges. I didn't think that was very nice. Then the clinical trial drug really messed up my nails. They became paper thin, flexible, and easy to tear. Yikes. I tried to keep them trimmed because any small rough spot could catch on something and become a tear, and any length could get banged and cause a big break. I also tried painting them with clear, tough polishes but that didn't seem to help. (Maybe I did not put on enough coats.)
Well, I am thrilled to report that my thumbs seem to be bouncing back. The nails on my thumbs are no longer completely bendy and paper thin. They are like normal.
Now I just have to wait for my other digits to catch up.
