Good afternoon, my name is Stan. I have a nail fungus with an unbearable twist. on my finger along side the nail a small narrow tube-like section of skin that is about the color of a blister. that runs from the side of the nail to a little red dot . the dot is incredibly sensitive, it turns brown in a couple days and looks like a splinter. I have tried to pull it out with tweezers. it feels hard and brittle sometimes and soft like thread other times. I have got little pieces (very tiny) to come out but it recedes inside my finger and disappears. it is so sensitive it has affected most all I do even warm water makes me want to jump out of my skin sometimes. it is not always that extreme but any7time I need to do tasks that require use of my finger tips it affects and sometime stop what I m doing. Any ideas? maybe a parasite. oh I have also pulled out a tiny thread smaller than hair about .25in long. hope you have good news.
