Wart?: Symptoms sound like a wart. Can't be sure without actually seeing your hand. Best to see your doctor for confirmation.

Cyst: Sebaceous cysts most often arise from swollen hair follicles. Skin trauma can also induce a cyst to form. A sac of cells is created into which a protein called keratin is secreted. These cysts are usually found on the face, neck, and trunk. They are usually slow- growing, painless, freely movable lumps beneath the skin. Occasionally, however, a cyst will become inflamed and tender.
