From the age of 50 I went to the doctor to ask what the crusty spots were coming through the skin I was told they were senile Watts warts and not to worry about them well I am now 86 and I still have them only they are much larger and crusty I I do not try to scrape them or interfere with them in any way but I would be much happier not to feel them and I want them to go away
