hi. i am 53 yrs old. my weight is 205. i am 5 feet 5 inches. i have had these little black pepper spots under the skin on my hands. when i pick them out, which i know i shouldnt, there are small holes in my skin. the skin then gets rough, like calluses. mainly in my kuckles. i have looked up several things on the computer, but to no avail. i have been to my family dr., and again to no avail. my hands are sore and red with these open areas. could you please me? thank you
