I have been dealing with my fingers splitting for more than 2o yrs now and I am just wonderingif it could be some kind of disease that I need to know about. Should I go to a Dermatologist for more accurate answers? My fingers split down the sides of them and tips.

That sounds painful. I have a similar thing, but not to that extent, and only on one finger. I usually just put polysporan or something similar on it, with a bandaide.

I would go see a dermatologist for sure. With the extent of the finger splitting he will be able to determine what is causing it, and likely have something to alleviate it.

vitamin K deficient, or is it vitamin E? It's found in fish oil. Just eat a tuna fish salad sandwich once in awhile or anchovy pizza or one of those fish fillet fast food meals.
