Both my pinkie toes on my feet are thick and some times peices will break off randomly and its been like sense I was younger. Is like a fungus or what?

Hyperkeratosis. This is thickened skin due to friction, possible fungal nail, or constant trauma from shoe. A podiatrist a foot doctor can address issue of gait, possible bone changes in those toes. Creams will be only marginally effective and the underlying issue of footwear and gait must be addressed.
