I have a small, whiteish, bump on my right index finger. It is very sensetive to touch. I first though I had burned my finger but couldn't rember any time I had done so. It has lasted about 10 days getting more sensitive each day though tapering off the last few days and remaining the same. It could be a plantar wart someone said but it is white and does not have much of a raised portion 1/32 of an inch in diameter. What to do?
