Thanks for writing in.
You are probably having a condition called leukonychia
and this can arise mostly from an injury
to the base of the nail. However, in some people it can occur due to a problem in the kidney
and the liver
function as well. I went through your history and i dont think its related to any liver or kidney problem.
You can expect it to get better within 4-8 weeks as that is the time it takes for the nails to grow back. No treatment is required as such.
Hope this helps.
