Our hands do almost everything for us, so when something goes wrong with them, we notice it all day long.
A swollen, red lump on the wrist or the back of the hand can make simple tasks like typing, cooking or carrying a bag painful.
Some of these lumps are ganglion cysts, small sacs of jelly-like fluid that grow out of a joint or tendon near the wrist.
Others are infected skin cysts or abscesses, which form when bacteria get trapped under the skin and the body fills the area with pus.
An infected lump is usually hot, red and tender, and it may develop a yellow head in the middle as the pus comes to the surface.
