I Am 79, And Have Been Experiencing Tingling On My

I am 79, and have been experiencing tingling on my left arm and torso for years, but small growths are appearing on my torso, across my back, up my scalp and are now appearing on my forehead. I have what feels like a neuropathy on my face...as if something were crawling on it. My dermatologist says nothing about it, but probably because it's getting so widespread and due to my age.
